Description:
------------
The HttpRequest-Class offers the methods getBody() and setBody(). The only link 
to these function is in a comment to the method HttpRequest::setRawPostData. Some 
other functions are missing, too. But especially setBody() is important if you 
begin using REST-API based applications like CouchDB or ElasticSearch, where you 
have to put JSON-Data in the HTTP-Body.

Test script:
---------------
<?php 
var_dump(get_class_methods('HttpRequest'));
//php -r "var_dump(get_class_methods('HttpRequest'));"

Expected result:
----------------
