How do Rev internet libraries work?

[Bernard Devlin]

Hi Tiemo,

Even if every network does have its own proxy, the IP address of each
proxy is unlikely to be the same (and the port may also be different).

If your application is on a network where the users are not allowed
direct access to the internet (either for security or caching
reasons), then somewhere in your app you would need to have a
preference for setting the IP address & port of the proxy.  Once the
user has entered that information, then your app would need to save it
as some kind of file (a stack or text file), or in the registry.  On
restart your app would re-set the proxy to the previously saved
settings.  Without this information, if there is a proxy then it's
unlikely your app would ever be able to make an internet connection
(assuming the proxy is there for security reasons).

This would be the same for many other applications I suspect.  I guess
it is possible to query the registry on Windows in order to find out
the proxy's IP address/port from there.  I don't work much with
Windows any more, but that information should be available on the
internet.

I hope that is the kind of information you want.
