Filter request with http:// in Nginx

  • 772

Is there a way to filter request that look like "GET http://example.com" but not filter one that look like "GET /index.html"? In other words what is the Nginx variable that can be used in the "If" clause?

The reason for asking this is that I see in my web site log multiple requests that look like: "GET http://somesite.com/proxyheader" from users that search for free proxy servers.

configuration nginx

    This works for me in 0.8.41:

    if ($request ~* "^[^ ]+[ ]+[^:]+://" ) { return 400; }

  2. Have you checked the variables in the nginx config?

    Can you show us an excerpt of your log files? Is the http://somesite... a parameter (http://example.com/http://seomsite...)?
