title: Intercept HTTP requests on linux
body: <p>I need something that can intercept HTTP requests, extract their information (content, destination,...), perform various analysing tasks, and finally determine if the request should be dropped or not. Legal requests must than be forwarded to the application.</p>
  
  <p>Basically, same functionalities as an IDS. But mind, I am NOT looking for a packet sniffer/filter. I want something that operates on the HTTP level.</p>
  
  <p>It should be implementable on linux and run on the same system as the application(s) to which the requests are headed.</p>
  
  <p>As a bonus, https could be supported (unencrypted viewing of the request content)</p>
