thanks again for your reply
yes i am able to connect database of my own server from clients server. i am also able to send clients server and key information (for checking purpose) to the file(which i have my own server). i can compare information which is received from clients server and which is in my own database.
But which thing i can not do is that after check if server name and key is matched, me should send 1 (any output) to client side and if information is not matched then me should send 0 (any output) to client side.
Because i want to stop him from further unauthorized use. Now i am unable to send information back to client side.
what firefox and advanced versions of IE not allowed is that
var url="http://www.example.php"
url=url+"?m="+m
url=url+"&sid="+Math.random()
now value of "m" cannot be send to
www.example.php
