title: Max size of URL parameters in _GET
body: <p>I am accessing a PHP server using REST: all data is passed in a GET request as URL parameters. One of the parameters arrives at the server in the query_string, but it is not in the _GET global. But shortening the parameter (the cutoff seems to be around 512 characters) lets it through.</p>
  
  <p>Assuming I have diagnosed the problem correctly, is there a way to change this maximum size? I have not found any explanation in the documentation, not even a mention of this limit. This is on Debian squeeze / Apache 2.2.16 / PHP 5.3.3.</p>
