Introduction

The HTTP extension aims to provide a convenient and powerful set of functionality for major applications.

The HTTP extension eases handling of HTTP URLs, dates, redirects, headers and messages in a HTTP context (both incoming and outgoing). It also provides means for client negotiation of preferred language and charset, as well as a convenient way to exchange arbitrary data with caching and resuming capabilities.

Also provided is a powerful request and parallel interface (PHP 5+), if the extension is built with cURL support.

Additionally to the API reference in this manual you can find information about how to install and configure as well as which global constants are predefined in the following sections:
