But your client could also use the getsockname() function!? Or do you
want to get the external IP for a client behind a NAT router? - But
behind a NAT you also have not much use of the external IP because the
other client is then connecting to the NAT router instead of to your
Also your extended client will have the problem, that it can do this
stuff only if your server administrator installs the module. I'd suggest
a solution that don't need changes on the server: Use a relaying
server where you put your data and the other site can get the data. E.g.
for file transfers just a webserver. You can put the data with WebDAV
and get it with normal http.
