Yes, it is, but not for those reasons. That entry was not put there simply because we had an HTTP proxy implementation, but because FTP requests can be routed through an HTTP proxy server just like HTTP and HTTPS requests. IOW, what do you do when the user specifies a HTTP proxy server as the FTP proxy. It is legal and valid to do that. What is happening in KDE now is that functionality is not supported for some unknown reason. > What I gather from this thread is that some HTTP proxies present FTP in HTML > format...

Since there is no input for specifying SOCKS proxy in the proxy configuration dialog, then I assume that the user is supposed to enter a non standard url, "socks://<host>:[<port>]", for specifying SOCKS proxy, correct ? If so, then ensuring FTP over SOCKS is not treated as FTP over HTTP is a simple one line fix in KProtocolManager::slaveProtocol. BTW, as it stands right now the ftp protocol does not support FTP over SOCKS. > proxiedBy should probably be per proxy protocol now. Sorry, but that would only serve to complicate proxy handling much more than the big mess it already is. Regards, Dawit A.
