kdelibs < 4.7:

its not supported. to make it work, you have to install an http server (like polipo) and point kde to it.

kdelibs == 4.7:

Good news is, socks proxy \’is\’ supported. Bad news is, there\’s no UI to configure it.

To configure it, add the following line to ~/.kde/share/config/kioslaverc file:

socksProxy=socks://HOST:PORT

Then, go to System Settings->Network Settings->Proxy and make sure the \’Manually specify the proxy settings\’ option is marked. (But dont click the \’Setup\’ button)
