   Title: 
     Proxy Detection 

   Version: 
     v2.0 

   Description: 
     This will detect any suspicious open socket 
     that the user is running and if found in an 
     array, it will not let the user proceed to 
     the website, with the ability to allow certain 
     hosts to pass the scan, and disallowing certain 
     hosts completely. You can define a redirect 
     page to redirect the user to upon open socket. 

   Usage: 
     Just include this page in any webpage you want protected.

ā) ports 1080 nekad netiks pārbaudīts un while pat izmetīs erroru pie x>=8

bē) what's the point? mēģinām noteikt, vai pie tevīm saitā ienāk proksis?

cē) tikuntā nevis $REMOTE_ADDR, bet gan $_SERVER['REMOTE_ADDR'] utml.
