Homepage cache and cookies

Fri Mar 25 22:09:01 UTC 2016

Hello John!

I think you can do this better with sessions in NginX.

I've made a script that checks if a client is a bot or not,
by testing if the Google Analytics cookie is here, or not.

If it is, the client can post a comment or login. If not, the
server is giving a fake page.

In my PHP script :
*****************************************************
		$host = $_SERVER['REMOTE_ADDR'];
		$session_id = session_id();
		$session_name = session_name();
		[…]
				if ( '' == $session_name ) {
					$session_name = '0';
					session_start();
					echo '<html><head></head><body><h1>server busy, come back later!</h1></body></html>';
					exit();
				}
		[…]
*****************************************************
All pages are cached ;-)

Regards,

Ph. Gras
