Better Parsing of URL parameters

[gimmel]

URL parameters are parsed in a wrong way sometimes. I experienced this problem with some URLs, for example 3sat and some youtube playlists.

http://www.3sat.de/mediathek/?mode=play&obj=48376
outputs "Unsupported URL: http://www.3sat.de/mediathek/?mode=play"

http://www.3sat.de/mediathek/?obj=48376
works

It seems like the URL is parsed with a (too) simple Regex. The URL parser should get the parameters by name, not by position or order.
