void httpAddCache (struct HttpRoute *route, cchar *methods, cchar *uris, cchar *extensions, cchar *types, MprTicks clientLifespan, MprTicks serverLifespan, int flags)

Add caching for response content.

Description:
This call configures caching for request responses. Caching may be used for any HTTP method, though typically it is most useful for state-less GET requests. Output data may be uniquely cached for requests with different request parameters (query, post, and route parameters).

When server-side caching is requested and manual-mode is not enabled, the request response will be automatically cached. Subsequent client requests will revalidate the cached content with the server. If the server-side cached content has not expired, a HTTP Not-Modified (304) response will be sent and the client will use its client-side cached content. This results in a very fast transaction with the client as no response data is sent. Server-side caching will cache both the response headers and content.

If manual server-side caching is requested, the response will be automatically cached, but subsequent requests will require the handler to explicitly send cached content by calling httpWriteCached.

If client-side caching is requested, a "Cache-Control" Http header will be sent to the client with the caching "max-age" set to the lifespan argument value (converted to seconds). This causes the client to serve client-cached content and to not contact the server at all until the max-age expires. Alternatively, you can use httpSetHeader to explicitly set a "Cache-Control header. For your reference, here are some keywords that can be used in the Cache-Control Http header.

"max-age" Maximum time in seconds the resource is considered fresh. "s-maxage" Maximum time in seconds the resource is considered fresh from a shared cache. "public" marks authenticated responses as cacheable. "private" shared caches may not store the response. "no-cache" cache must re-submit request for validation before using cached copy. "no-store" response may not be stored in a cache. "must-revalidate" forces clients to revalidate the request with the server. "proxy-revalidate" similar to must-revalidate except only for proxy caches.

Use client-side caching for static content that will rarely change or for content for which using "reload" in the browser is an adequate solution to force a refresh. Use manual server-side caching for situations where you need to explicitly control when and how cached data is returned to the client. For most other situations, use server-side caching.
Parameters:
routeHttpRoute object.
methodsList of methods for which caching should be enabled. Set to a comma or space separated list of method names. Method names can be any case. Set to null or "*" for all methods. Example: "GET, POST".
urisSet of URIs to cache. If the URI is set to "*" all URIs for that action are uniquely cached. If the request has POST data, the URI may include such post data in a sorted query format. E.g. {uri: /buy?item=scarf&quantity=1}.
extensionsList of document extensions for which caching should be enabled. Set to a comma or space separated list of extensions. Extensions should not have a period prefix. Set to null or "*" for all extensions. Example: "html, css, js".
typesList of document mime types for which caching should be enabled. Set to a comma or space separated list of types. The mime types are those that correspond to the document extension and NOT the content type defined by the handler serving the document. Set to null or "*" for all types. Example: "image/gif, application/x-php".
clientLifespanLifespan of client cache items in milliseconds. If not set to positive integer, the lifespan will default to the route lifespan.
serverLifespanLifespan of server cache items in milliseconds. If not set to positive integer, the lifespan will default to the route lifespan.
flagsCache control flags. Select HTTP_CACHE_MANUAL to enable manual mode. In manual mode, cached content will not be automatically sent. Use httpWriteCached in the request handler to write previously cached content.

Select HTTP_CACHE_CLIENT to enable client-side caching. In this mode a "Cache-Control" Http header will be sent to the client with the caching "max-age". WARNING: the client will not send any request for this URI until the max-age timeout has expired.

Select HTTP_CACHE_RESET to first reset existing caching configuration for this route.

Select HTTP_CACHE_ALL, HTTP_CACHE_ONLY or HTTP_CACHE_UNIQUE to define the server-side caching mode. Only one of these three mode flags should be specified.

If the HTTP_CACHE_ALL flag is set, the request params (query, post data, and route parameters) will be ignored and all requests for a given URI path will cache to the same cache record.

Select HTTP_CACHE_UNIQUE to uniquely cache requests with different request parameters. The URIs specified in uris should not contain any request parameters.

Select HTTP_CACHE_ONLY to cache only the exact URI with parameters specified in uris. The parameters must be in sorted www-urlencoded format. For example: /example.esp?hobby=sailing&name=john.
Returns:
A count of the bytes actually written.

void httpError (HttpConn *conn, int status, cchar *fmt, ...)

Error handling for the connection.

Description:
The httpError call is used to flag the current request as failed. If httpError is called multiple times, those calls are ignored and only the first call to httpError has effect. This call will discard all data in the output pipeline queues. If some data has already been written to the client the connection will be aborted so the client can get some indication that an error has occurred after the headers have been transmitted.
Parameters:
connHttpConn connection object created via httpCreateConn
statusHttp status code. The status code can be ored with the flags HTTP_ABORT to immediately abort the connection or HTTP_CLOSE to close the connection at the completion of the request.
fmtPrintf style formatted string.

Valid states are: HTTP_STATE_BEGIN, HTTP_STATE_CONNECTED, HTTP_STATE_FIRST, HTTP_STATE_CONTENT, HTTP_STATE_READY, HTTP_STATE_RUNNING, HTTP_STATE_FINALIZED and HTTP_STATE_COMPLETE. A request will always visit all states and the notifier will be invoked for each and every state. This is true even if the request has no content, the HTTP_STATE_CONTENT will still be visited.
  • HTTP_EVENT_READABLE There is data available to read
  • HTTP_EVENT_WRITABLE The outgoing pipeline can absorb more data
  • HTTP_EVENT_ERROR The request has encountered an error
  • HTTP_EVENT_DESTROY The connection structure is about to be destoyed

HttpQueue

HttpQueue

Queue object.

Description:
The request pipeline consists of a full-duplex pipeline of stages. Each stage has two queues, one for outgoing data and one for incoming. A HttpQueue object manages the data flow for a request stage and has the ability to queue and process data, manage flow control, and schedule packets for service.

Queue's provide open, close, put, and service methods. These methods manage and respond to incoming packets. A queue can respond immediately to an incoming packet by processing or dispatching a packet in its put() method. Alternatively, the queue can defer processing by queueing the packet on it's service queue and then waiting for it's service() method to be invoked.

If a queue does not define a put() method, the default put() method will be used which queues data onto the service queue. The default incoming put() method joins incoming packets into a single packet on the service queue.

Data flows downstream from one queue to the next queue linked via the nextQ field.

Write a block of data onto the end of the queue. This will queue the data an may initiaite writing to the connection if the queue is full. Data will be appended to last packet in the queue if there is room. Otherwise, data packets will be created as required to store the write data. This call operates in buffering mode by default unless either the HTTP_BLOCK OR HTTP_NON_BLOCK flag is specified. When blocking, the call will either accept and write all the data or it will fail, it will never return "short" with a partial write. In blocking mode (HTTP_BLOCK), it block for up to the inactivity timeout specified in the conn->limits->inactivityTimeout value. In non-blocking mode (HTTP_NON_BLOCK), the call may return having written fewer bytes than requested. In buffering mode (HTTP_BUFFER), the data is always absorbed without blocking and queue size limits are ignored. Data written after httpFinalize, httpFinalizeOutput or httpError is called will be ignored.
Parameters:
qQueue reference.
bufBuffer containing the write data.
sizeof the data in buf.
flagsSet to HTTP_BLOCK for blocking operation or HTTP_NON_BLOCK for non-blocking. Set to HTTP_BUFFER to buffer the data if required and never block. Set to zero will default to HTTP_BUFFER.

The "directory" rule tests if the condition argument is a directory. The form of the "directory" rule is: "directory pathString". For example: "directory /stuff/${request:pathInfo}.txt"

The "exists" rule tests if the condition argument is present in the file system. The form of the "exists" rule is: "exists pathString". For example: "exists ${request.filename}.gz",

The match directory tests a regular expression pattern against the rest of the condition arguments. The form of the match rule is: "match RegExp string". For example: "match https ${request.scheme}".
detailsCondition parameters. See httpSetRouteTarget for a list of the token values that can be included in the condition rule details.
flagsSet to HTTP_ROUTE_NOT to negate the condition test.

char * httpLink (HttpConn *conn, cchar *target, MprHash *options)

Create a URI link.

\par \b Description: Create a URI link by expansions tokens based on the current request and route state. The target parameter may contain partial or complete URI information. The missing parts are supplied using the current request and route tables. The resulting URI is a normalized, server-local URI (that begins with "/"). The URI will include any defined route prefix, but will not include scheme, host or port components
Parameters:
connHttpConn connection object.
targetThe URI target. The target parameter can be a URI string or JSON style set of options. The target will have any embedded "{tokens}" expanded by using token values from the request parameters. If the target has an absolute URI path, that path is used directly after tokenization. If the target begins with "~", that character will be replaced with the route prefix. This is a very convenient way to create application top-level relative links.

If the target is a string that begins with "{AT}" it will be interpreted as a controller/action pair of the form "{AT}Controller/action". If the "controller/" portion is absent, the current controller is used. If the action component is missing, the "list" action is used. A bare "{AT}" refers to the "list" action of the current controller.

If the target starts with "{" it is interpreted as being a JSON style set of options that describe the link. If the target is a relative URI path, it is appended to the current request URI path.

If the is a JSON style of options, it can specify the URI components: scheme, host, port, path, reference and query. If these component properties are supplied, these will be combined to create a URI.

If the target specifies either a controller/action or a JSON set of options, The URI will be created according to the route URI template. The template may be explicitly specified via a "route" target property. Otherwise, if an "action" property is specified, the route of the same name will be used. If these don't result in a usable route, the "default" route will be used.

These are the properties supported in a JSON style "{ ... }" target:
  • scheme String URI scheme portion
  • host String URI host portion
  • port Number URI port number
  • path String URI path portion
  • reference String URI path reference. Does not include "#"
  • query String URI query parameters. Does not include "?"
  • controller String Controller name if using a Controller-based route. This can also be specified via the action option.
  • action String Action to invoke. This can be a URI string or a Controller action of the form {AT}Controller/action.
  • route String Route name to use for the URI template
optionsHash of option values for embedded tokens.
Returns:
A normalized, server-local Uri string.

void httpSetRoutePattern (HttpRoute *route, cchar *pattern, int flags)

Set the route pattern.

Description:
This call defines the route regular expression pattern that is used to match against the request URI. The route pattern is an enhanced JavaScript-compatibile regular expression. It is enhanced by optionally embedding braced tokens "{name}" in the patter. During request URI matching, these tokens are extracted and defined in the request params and are available to the request. The normal regular expression repeat syntax also uses "{}". To use the traditional (uncommon) repeat syntax, back quote with "\\". Sub-expressions and token expressions are also available in various rules as numbered tokens "$1". For example: the pattern "/app/(.*)(.html)$" will permit a file target "$1.${request.Language=fr}.$2".
Parameters:
routeRoute to modify.
patternRoute regular expression pattern.
flagsSet to HTTP_ROUTE_NOT to negate the pattern match result.

int httpSetRouteTarget (HttpRoute *route, cchar *name, cchar *details)

Set a route target.

Description:
This configures the route pipeline by defining a route target. The route target is interpreted by the selected route handler to process the request. Route targets can contain symbolic tokens that are expanded at run-time with their corresponding values. There are three classes of tokens:
  • System and Route varibles - such as DOCUMENTS_DIR, HOME_DIR, BIN_DIR, PRODUCT, OS, VERSION.
  • Route URI tokens - these are the braced tokens in the route pattern.
  • Request fields - these are request state and property values.
System and URI tokens are of the form: "${token}" where "token" is the name of the variable or URI token. Request fields are of the form: "${family:name=defaultValue}" where the family defines a set of values. If the named field is not present, an optional default value "=defaultValue" will be used instead. These supported request field families are:
  • header - for request HTTP header values
  • param - for request params
  • query - for request query field values
  • request - for request details
  • Any URI pattern token
For example: "run ${header:User-Agent}" to select the client's browser string passed in the HTTP headers. For example: "run ${field:name}" to select the client's browser string passed in the HTTP headers. For example: "run ${name}.html" where {name} was a token in the route pattern. For example: "run ${name}.html" where {name} was a token in the route pattern. The supported request key names are:
  • clientAddress - The client IP address
  • clientPort - The client port number
  • error - Any request or connection error message
  • ext - The request extension
  • extraPath - The request extra path after the script extension
  • filename - The mapped request filename in physical storage
  • language - The selected language for the request
  • languageDir - The langauge directory
  • host - The host name owning the route for the request
  • method - The request HTTP method
  • originalUri - The original, pre-decoded URI
  • pathInfo - The path portion of the URI after the host and port information
  • prefix - The route prefix
  • query - The request query information
  • reference - The request reference fragment. This is the URI portion after "#"
  • scheme - The request protocol scheme. E.g. "http"
  • scriptName - The request script or application name
  • serverAddress - The server IP address
  • serverPort - The server port number
  • uri - The full request URI. May be modified by routes, handlers and filters
Also see httpMakePath for additional tokens (DOCUMENTS_DIR, HOME_DIR, BIN_DIR, PRODUCT, OS, VERSION).
Parameters:
routeRoute to modify.
nameTarget rule to add. Supported update rules include: "close", "redirect", "run" and "write".

The "close" rule is used to do abortive closes for the request. This is useful for ward off known security attackers. For example: "close immediate". The "close" rule takes no addition parameters.



The "redirect" rule is used to redirect the request to a new resource. For example: "redirect 302 /tryAgain.html". The "redirect" takes the form: "redirect status URI". The status code is used as the HTTP response code. The URI can be a fully qualified URI beginning with "http" or it can be a relative URI.

The "run" target is used to run the configured handler to respond to the request. For example: "file ${DOCUMENTS}/${request.uri}.gz".

The "write" rule is used to write literal data back to the client. For example: "write 200 Hello World\r\n". The "write" rule takes the form: "write [-r] status message". Write data is by default HTML encoded to help eliminate XSS security exposures. The "-r" option selects "raw" output and bypasses the HTML encoding of the write data string.

WARNING: Take great care when using raw writes with tokens. Write data is not HTML encoded and echoing back to raw data to the client can cause XSS and other security issues. The status field defines the HTTP status code to use in the response.

"Zero" if successful, otherwise a negative MPR error code.

HttpStage

HttpStage

Pipeline Stages.

Description:
The request pipeline consists of a full-duplex pipeline of stages. Stages are used to process client HTTP requests in a modular fashion. Each stage either creates, filters or consumes data packets. The HttpStage structure describes the stage capabilities and callbacks. Each stage has two queues, one for outgoing data and one for incoming data.

Stages provide callback methods for parsing configuration, matching requests, open/close, run and the acceptance and service of incoming and outgoing data.
See Also:

API Stability:

Fields:
void(*close)(HttpQueue *q) Close the stage. Description:Close the stage and cleanup any request resources. qQueue instance objectAPI Stability:Evolving
MprHash *extensions Matching extensions for this filter.
intflags Stage flags.
void(*incoming)(HttpQueue *q, HttpPacket *packet) Process incoming data. Description:Accept an incoming packet of data. Filters and handlers recieve packets via their incoming callback. They can choose to immediately process or forward the packet, or they can queue the packet on their queue and schedule their incomingService callback for batch processing of all queued packets. This is a common pattern where the incoming routine is not used and packets are automatically queued and the incomingService callback is used to process. Not used by connectors. qQueue instance object packetPacket of dataAPI Stability:Evolving
void(*incomingService)(HttpQueue *q) Service the incoming data queue. Description:This callback should service packets on the queue and process or forward as appropriate. A service routine should check upstream queues by calling httpWillNextQueueAcceptPacket before forwarding packets to ensure they do not overfow upstream queues. qQueue instance objectAPI Stability:Evolving
int(*match)(struct HttpConn *conn, struct HttpRoute *route, int dir) Match a request. Description:This routine is invoked to see if the stage wishes to handle the request. For handlers, the match callback is invoked when selecting the appropriate route for the request. For filters, the callback is invoked subsequently when constructing the request pipeline. If a filter declines to handle a request, the filter will be removed from the pipeline for the specified direction. The direction argument should be ignored for handlers. Handlers and filters must not actually handle the request in the match callback and must not call httpError. Errors can be reported via mprError. Handlers can defer error reporting until their start callback. connHttpConn connection object routeRoute object dirQueue direction. Set to HTTP_QUEUE_TX or HTTP_QUEUE_RX. Always set to HTTP_QUEUE_TX for handlers. HTTP_ROUTE_OK if the request is acceptable. Return HTTP_ROUTE_REROUTE if the request has been rewritten. Return HTTP_ROUTE_REJECT it the request is not acceptable.API Stability:Evolving
MprModule *module Backing module.
char *name Stage name.
void(*open)(HttpQueue *q) Open the stage. Description:Open the stage for this request instance. A handler may service the request in the open routine and may call httpError if required. qQueue instance objectAPI Stability:Evolving
void(*outgoing)(HttpQueue *q, HttpPacket *packet) Process outgoing data. Description:Accept a packet as outgoing data. Not used by handlers as handler generate packets internally. Filters will use this entry point to accept outgoing packets. Filters can choose to immediately process or forward the packet, or they can queue the packet on their queue and schedule their outgoingService callback for batch processing of all queued packets. This is a common pattern where the outgoing routine is not used and packets are automatically queued and the outgoingService callback is used to process data. qQueue instance object packetPacket of dataAPI Stability:Evolving
void(*outgoingService)(HttpQueue *q) Service the outgoing data queue. Description:This callback should service packets on the queue and process or forward as appropriate. A service routine should check downstream queues by calling httpWillNextQueueAcceptPacket before forwarding packets to ensure they do not overfow downstream queues. qQueue instance objectAPI Stability:Evolving
char *path Backing module path (from LoadModule).
void(*ready)(HttpQueue *q) The request is now fully ready. Description:This callback will be invoked when all incoming data has been received. The ready callback will not be called if the request already has an error. If a handler finishes processing the request, it should call httpFinalizeOutput in the ready routine. qQueue instance objectAPI Stability:Evolving
void *stageData Private stage data.
void(*start)(HttpQueue *q) Start the handler. Description:The start callback is primarily responsible for starting the request processing. Depending on the request Content Type, the request will be started at different times. Form requests with a Content-Type of "application/x-www-form-urlencoded", will be started after fully receiving all input data. Other requests will be started immediately after the request headers have been parsed and before receiving input data. This enables such requests to stream large quantities of input data without buffering. The handler start callback should test the HTTP method in conn->rx->method and only respond to supported HTTP methods. It should call httpError for unsupported methods. The start callback will not be called if the request already has an error. qQueue instance objectAPI Stability:Evolving
void(*writable)(HttpQueue *q) The outgoing pipeline is writable and can accept more response data. Description:This callback will be invoked after all incoming data has been receeived and whenever the outgoing pipeline can absorb more output data (writable). As such, it may be called multiple times and can be effectively used for non-blocking generation of a response. The writable callback will not be invoked if the request output has been finalized or if an error has occurred. qQueue instance objectAPI Stability:Evolving

HttpWebSocket

HttpWebSocket

WebSocket Service to implement the WebSockets RFC 6455 specification for client and server communications.

Description:
WebSockets is a technology providing interactive communication between a server and client. Normal HTML connections follow a request / response paradigm and do not easily support asynchronous communications or unsolicited data pushed from the server to the client. WebSockets solves this by supporting bi-directional, full-duplex communications over persistent connections. A WebSocket connection is established over a standard HTTP connection and is then upgraded without impacting the original connection. This means it will work with existing networking infrastructure including firewalls and proxies.
