Hi guys,

I am getting lot of traffic to my php pages but without the variable $_SERVER['HTTP_HOST'] setted.

This traffic is like 1 hit per second. I don't know what it could be, but for reducing server load i am doing this at the top of every php pages:

if (!isset($_SERVER['HTTP_HOST']))
    exit;

Do u know what could cause this? Is it safe to exit whenever http_host is not setted? Can a normal user visit my pages without setting http_host?

PHP version: 5.2.0-8, Apache: 2.2.3

Thanks
