Hi
I'm trying to achieve a kind of proxy/filter effect for a specific TCP/IP
port. I want my application to act as a server to all other applications on
the system for that specific port.
For example, Safari connects to site www.whatever.com on port 412. My
application is intercepting on port 412, so instead of getting a response
from www.whatever.com, my application would serve as the server (and
possibly open a separate connection from itself to that site).
The type of behavior I'm after is similar to what PGP Desktop does with
encrypting/decrypting e-mail.
I'm looking for a suggestion on a framework/API I could use to do something
like this. I'm not too sure whether there's something in the Cocoa
frameworks that could do this, or whether I should be looking at something
in BSD sockets.
Any suggestions would be appreciated.
Regards
Lionel
