how to access url when we are behind a proxy ?

Commented:
Hmm.. I think accessing the outside should be transparent
to the program. Did you try to access the outside and was
unsuccessful?
I think the proxy should be decided by the browser...
I can't find any function in Java to setup the proxy server for URLConnection either.

I was reading up on the book Migrating from Java 1.0 to Java 1.1
about the proxy. It made a mention of it, but did not specify an
example of how it can be done. I'll include bits and piece of information
and hope that you can benefit from it:

"Java 1.0 does support a way to enhance the acapabilities of the Socket-
based classes. You need to implement the java.net.SocketImpl class and
the java.net.SocketImplFactory interface. It gives you the ability to add functionality
for environment-specific situations in which you need to do something environmentally
specific for a network connection to take place. An excellent example of this would be
when you establish a connection to the Internet behind a firewall where all communication
needs to go through a proxy.

In Java 1.1, it has provided extendability of sockets. Extendable socket-based classes
are much more versatile and they are more focused on helping you add layers of
functionality, rather than just providing a way to compensate for the inconsistencies
between environments. It is still recommended that you use the subclassing -
SocketImpl apporach for any environmentally specific tasks.

P. 360/361.     If you are interested, you might want to check them out at your local
bookstore.
