Redmine

Starting from Redmine 2.0 the web context does not recogonize a sub directory. See also Thread http://www.redmine.org/boards/2/topics/30676?r=30981#message-30981.

The problem seems to be that the ActionController within rails 3. It does no longer consider the variable
ActionController::AbstractRequest.relative_url_root as web context root for the routes.

I managed to get around that problem by modifying the config/routes.rb:
