Description Ralf Hildebrandt 2006-03-09 22:34:16 UTC

Version:            (using KDE KDE 3.5.1)
Installed from:    Debian testing/unstable Packages

Our proxy autoconfiguration ULR is http://proxy.charite.de
All browsers except for konqueror and safari can use it; konqueror and safari require to form http://proxy.charite.de/proxy.pac (this is where http://proxy.charite.de redirects to). When these two browsers are configured to use http://proxy.charite.de, they simply freeze.

Comment 6 Malte Cornils 2006-07-29 17:19:11 UTC

I think the code responsible for this behaviour can be found at kdelibs/kio/misc/kpac/downloader.cpp, in method Downloader::download().

KIO::get(url, false, false) is called there, and I suppose that KIO::get() does not follow redirects?

I don't see why not, though. The http kioslave actually supports redirects perfectly. Anyone?

Comment 7 Malte Cornils 2006-07-29 17:40:08 UTC

BTW, Alt-F2 and typing in the (to be rewritten) URL works great and opens up kwrite with the proxy autoconfig script. However, Krun uses the same

KIO::TransferJob *job = KIO::get( m_strURL, false /*reload*/, m_bProgressInfo );

as our code here. *sigh*

Comment 8 Ralf Hildebrandt 2006-12-13 13:52:32 UTC

Still there in 3.5.5
