title: $_SERVER["CONTENT_LENGTH"] not set
body: <p>Is there any php.ini setting which could cause <code>isset($_SERVER["CONTENT_LENGTH"])</code> to never be set on one server, but work fine on another, where the application code is the same and php.ini upload settings are the same? In an uploader library I'm using, the content length check always fails because of this issue. On PHP5.3, CentOS and Apache. Thanks for any help</p>
  
  <p>EDIT: I should add that in the Request Headers, Content-Length:33586 - but when trying to process <code>$_SERVER["CONTENT_LENGTH"]</code>, it isn't set. </p>
