Bug 188435

Version:            (using KDE 4.2.1)
OS:                Linux
Installed from:    Fedora RPMs

The simplest example:

open http://www.veryicon.com/icon/bah-bz2.html in Konqueror, it will redirect to http://www.veryicon.com:80/icons/file-type/archives/bah-bz2.html

Mind the [:80] part of the new URL.

Consequences:
1) KWallet authentication fails.
2) Referrer information breaks.
3) History gets filled with erroneous entries.

This problem is often visible on sites which redirect upon authentication.

I can report other websites which cause such misbehaviour.

telnet session shows no problems and no explicit port direction:

telnet www.veryicon.com 80
Trying 74.53.9.254...
Connected to www.veryicon.com.
Escape character is '^]'.
GET /icon/bah-bz2.html HTTP/1.0

Having investigated this bug for some time I found out that this problems happens for all sites which use HTTP code 301 redirection.

E.g. http://www.dmi.dk/dmi/mobil/ redirects to http://www.dmi.dk:80/dmi/mobil/mobil/til_lands.htm.

This bug also occurs for 302 redirects:

In this case Konqueror redirects to http://example.com:80/login.shtml
