Hi, just upgraded an app from Rails 2.1.0 to 2.2.2 and finding my routes  
stopped working

URL which doesn’t match is:  
[http://blah/blog/auth/login](http://blah/blog/auth/login)

Route is:  
map.connect ‘blog/:controller/:action/:id’, :requirements =\>  
{:controller =\> /(auth|asdf)/}

In fact, neither does this match:  
map.connect ‘blog/:controller/:action/:id’, :requirements =\>  
{:controller =\> /(auth)/}

But this does:  
map.connect ‘blog/:controller/:action/:id’, :requirements =\>  
{:controller =\> /auth/}

So the problem seems to be that “( )” syntax is breaking the regexp  
parsing. Curiously though the regexp _does_ work for link generation,  
it’s only route recognition which breaks

Can anyone give me a quick workaround for this, quite a lot or routes to  
alter otherwise…

Thanks
