detect proxy

Hi Sonjaya, Here is how i detect a proxy / user external ip and internal ip I use the global variable catched by PHP from the web server, the web server that i use is Apache i don't know about your's but it might work. There are tonns of available information here is some that i have debugged If you get a User Browser : $GLOBALS[HTTP_USER_AGENT] External IP : $GLOBALS[REMOTE_ADDR] Internal IP : $GLOBALS[HTTP_X_FORWARDED_FOR] Proxy : $GLOBALS[HTTP_VIA] Please notice that you might get all, same or partial information from the user i think the only one that you can trust 100% is the External IP since this is basic TCP/IP all the rest might be empty or with invalid values. Microsoft ISA proxy at my job for example does not foward the internal user IP. try something print_r($GLOBALS) to check out all the avaliable informations you could do something like this if ( $GLOBALS[HTTP_VIA] == "" ) { echo "User Proxy is Not Available <br>"; } else { echo "User Proxy: $GLOBALS[HTTP_VIA] <br>"; } Hope this help you !
