Custom URLs in Rails

like for example virb.com/yourURLHere, how is this accomplished...
I've been searching for a bit but I haven't found a solution.

Thanks

take a look at some of these solutions

Let me rephrase....

When I say custom URL I mean... that http://www.yoursite.com/controller
is the regular format.... What if it was http://www.yoursite.com/your_screen_name,
and then route that to the profile controller and index action for
example.

Make sense?

Read up on routing. There is a file called routes.rb in your config
directory that does this mapping for you.

This is a good place to start.

Thanks for the help... BTW it is my first time even using rails =)

heres' what I finally was able to do

map.connect '*path', :controller => 'profile', :action => 'index'

at the bottom of routes...

Seems to work. Cheers
