Version: (using KDE 4.2.2) Installed from: Debian testing/unstable Packages Currently proxies for which the client-proxy connection is ssl-encrypted don't work. I tried with the deleGate proxy (http://www.delegate.org) but I suppose it's the same with a squid using ssl.
Assuming you are talking about encrypted proxy address (i.e. HTTPS), is this still an issue in recent versions of KDE, v4.6 and up ?
Feel free to reopen this ticket if the issue persists in th latest releases of KDE, i.e. v4.7 & up.
