The HTTP extension for PHP aims to provide a convenient and powerful set of functionality for one of PHP's major applications. It eases handling of HTTP URLs, dates, redirects, headers, and messages, provides means for negotiation of clients' preferred language and charset, as well as a convenient way to send any arbitrary data with caching and resuming capabilities. It provides powerful request functionality if built with CURL support. Parallel requests are available for PHP 5 and greater.

In the latest release, a bug where http_negotiate does not return default value on non-match has been fixed. the SSL library detection for libcurl >= 7.16.2 has been fixed, and the max_recv_speed and max_send_speed request options have been removed again due to LFS dependence.
