Improved persistent connections.
The following describes the original HTTP/1.0 form of persistent connections.
Use persistent connections to proxy.
Additionally, when using persistent connections it is.
Persistent connections have no effect if PHP is used as a CGI program.
Additionally, when using persistent connections it is recommended to enable.
Wget 1.7, released June 2001, introduced SSL support,cookies, and persistent connections.
HTTP/1.1 applications that do not support persistent connections MUST include the"close" connection option in every message.
The Keep-Alive extension to HTTP, as defined by the HTTP/1.1 draft,allows persistent connections.
However, talking to proxies is the most important use of persistent connections, so that prohibition is clearly unacceptable.
Clients that use persistent connections SHOULD limit the number of simultaneous connections that they maintain to a given server.
Persistent'=>(bool): use or not persistent connections to this.
The use of persistent connections places no requirements on the length(or existence) of this timeout for either the client or the server.
This is because PHPapplications may continue to successfully reuse persistent connections by authenticating with the old password.
The use of persistent connections places no requirements on the length(or existence) of this timeout for either the client or the server.
For HTTP/1, 74% of our activeconnections carry just a single transaction- persistent connections just aren't as helpful as we all want.
A client that supports persistent connections MAY"pipeline" its requests(i.e., send multiple requests without waiting for each response).
A significant difference between HTTP/1.1 andearlier versions of HTTP is that persistent connections are the default behavior of any HTTP connection. .
Prior to persistent connections, a separate TCP connection was established to fetch each URL, increasing the load on HTTP servers and causing congestion on the Internet.
Some clients andservers may wish to be compatible with some previous implementations of persistent connections in HTTP/1.0 clients and servers.
HTTP/1.0 experimental implementations of persistent connections are faulty, and the new facilities in HTTP/1.1 are designed to rectify these problems.
This maps directly to Async::HTTP::Client close and should improve support for adapters that support persistent connections(including HTTP/2).
HTTP/1.1 applications that do not support persistent connections MUST include the"close" connection option in every message.
Persistent connections Short-lived connections have two major hitches: the time taken to establish a new connection is significant, and performance of the underlying TCP connection gets better only when this connection has been in use for some time warm connection. .
That means that you should always be able to replace persistent connections with non-persistent connections, and it won't change the way your script behaves.
Clients which assume persistent connections and pipeline immediately after connection establishment SHOULD be prepared to retry their connection if the first pipelined attempt fails.
Implementation note: In HTTP implementations which do not use persistent connections, the server ordinarily expects to be able to signal end of data by closing the connection. .
Additionally, when using persistent connections it is recommended to enable Keep-Alive HTTP requests as described in the configuration section- otherwise persistent connections might have little or no effect.
SDK is built on Guzzle v3, and utilizes many of its features,including persistent connections, parallel requests, events and plugins(via Symfony2 EventDispatcher), service descriptions, over-the-wire logging, caching, flexible batching, and request retrying with truncated exponential back off.
