You need to enable module mod_headers. That can be done by typing: Code: a2enmod headers Code: sudo /etc/init.d/apache2 restart Than you can manipulate headers. Google http RequestHeader
Now it's up to you to manipulate headers, you can do that through htaccess files. Than there is online tools that can be used to check headers. You can even use telnet for that. Here is some snippets on how you can play with headers.
Hi there, It's still not clear how to get the apache_request_headers to work. I got this from a scripter: "Need to enable apache_request_headers() function in your server php". How to get this done? Rudolf.
