Sabre/http provides a toolkit to ease the work with HTTP protocol.

This library is a wrapper around the following PHP constructs:

For Input:
* $_GET
* $_POST
* $_SERVER
* php://input or $HTTP_RAW_POST_DATA.
For output:
* php://output or echo.
* header()
It provides a Request object, and a Response object. The objects are extensible and easily mockable.
