Proxies

From the CouchSurfing Wiki, an informal workspace which anyone can edit.

CouchSurfing uses their users' IP address to find out their location.

Location is determined based on the IP address (PHP "REMOTE_ADDR" environement variable). As some users are always using their ISP proxy sever to surf the web, it is always reported that they login somewhere else. Most proxy servers report the real client IP address in HTTP headers, and this info is available in the "HTTP_X_FORWARDED_FOR" PHP environement variable. We could use this IP instead if it is provide.

Downside of this method is it can be faked by sending false HTTP headers, whereas the "REMOTE_ADDR" can not. We can combine this with a list of "trusted" proxies, which is probably good to have anyway.

For untrusted proxies it can mark the location as "probably". Any volunteers for maintaining such lists?
