Sockets and firewalls

[Thomas Dybdahl Ahle]

Hi, I'm writing a program using sockets, but it doesn't work if the
host/server has a firewall/router (don't know if only the client has a
firewall)
I get a "unable to open IO stream" error at runtime. Is their anyway to
handle this? I heard something about proxies? Is it the thing?
If it is, then how do you use them with sockets in java?

world gone digital. They are in many ways similar to the priests and monks of
Europe's Dark Ages; they are the only ones with the training and insight
to read and interpret the "scripture" of this age.

Re: Sockets and firewalls

I also heard somewhere, that if I wan't to use proxies, then I'll have to
do httprequests, which just seam to be strings starting with GET/PUT.
This sounds fine, but how does it work i real life?
Will I have to use some special classes or set some special arguments?
