Routes in Ruby on Rails are case sensitive. It seems someone brought this up before, and it has been labeled will not fix.

That strikes me as unfortunate, as I don't really see any upside on my own application for routes to be case sensitive, while on the downside it creates a potential for confusion and a general appearance of lack of polish in my opinion.
What's the best way to make my routes case insensitive?
I found this tip on a Google search:
map.connect "web_feeds/:action", :controller => 'web_feeds', :action => /[a-z_]+/i
This is clever, but it still leaves the web_feeds portion of the url case sensitive. I don't see any similar way around this, however, without entering in each possible combination of wEb_feEds manually, but that is obviously a horrible solution for any number of reasons.
I've just has the same problem, and solved it using middleware - have a look here:
