Routes and urls: www.example.com

I'm building an application that stores links, but i've run into a
problem with routing. If my routes.rb looks like this:

  map.widget '/widget/show/:url', :controller => "widget", :action =>
"show"

then when i go to /widget/show/www.example.com then i get an error. If
i change the route to:

  map.widget '/widget/show', :controller => "widget", :action => "show"

and i enter in /widget/show?url=www.example.com then everything works
great, but i'm currious if there is anything i can do to make the first
routing method work?

You might want to try:

map.widget '/widget/show/*url', :controller => 'widget', :action =>
'show'

and see if that works. I seem to recall that the dots are the issue,
as the router typically uses them to separate formats from request
params.

That Worked!! Now it looks even better than it did before, I can go to
/widget/show/www.example.com without that nasty ?url= . Good Work!! I
also have to admit that i should have RTFM
http://guides.rubyonrails.org/routing.html mentions this technique,
apparently its called Route Globbing and not found until a few minutes
of reading. Thanks again for your help Matt!!
