I have a PHP script that tries to check $_SERVER['HTTP_IF_NONE_MATCH'] and/or $_SERVER['HTTP_IF_MODIFIED_SINCE'], but neither one is ever set, even if the client sent the If-None-Match or If-Modified-Since headers.
Since the point of the If-None-Match and If-Modified-Since headers is to enable the server to respond with a 304 instead of sending the requested resource all over again every single time, it would be nice (and probably to x10Hosting's own benefit) if it these headers were passed to PHP correctly. Could this change be made?
