In our web based system, I have a jsp page that creates a web page 
containing an applet. This applet is used for connecting our dataserver 
over tcp sockets. One of our clients use proxy for internet connection, so 
applet needs the proxy information of RemoteClient. I dont want to bother 
our clients with the details of service communication and i want to gather 
this information from clients browser with clientside scripting. 
But i have no idea how can i get this information from  IE!
is there anyone who can solve this case?

thanks for your interests.
