Comment:
Explained meaning of 200 code

  {{{
  63.251.56.142 - - [25/Jul/2002:12:48:04 -0700] "GET http://www.yahoo.com/ HTTP/1.0" 200 1456 
  }}}
+ 
+ For this log line, the ''200'' code (second to last field in this example) indicates that the proxy request was successful.
  
  This is usually the result of malicious clients trying to exploit open proxy servers to access a website without revealing their true location. They could be doing this to manipulate pay-per-click ad systems, to add comment or link-spam to someone else's site, or just to do something nasty without being detected.
