I have a apache2 virtual host configured but I suffer a attack with thousands or request like "POST http://check2.zennolab.com/proxy.php HTTP/1.1" 200 115 "GET http://hartford.craigslist.org/fuo/3293382678.html HTTP/1.1" 200 2223
anybody knows what kind of attack is this? how I do to prevent?
EDIT:
Warning
Do not enable proxying with ProxyRequests until you have secured your server. Open proxy servers are dangerous both to your network and to the Internet at large.
of course it had enabled
