link_to wrong path...

HI guys, I'm starting with RoR and I figured I'd jump on the facebook
bandwagon and make a little application... my problem is when using
link_to inside my application I get wrong paths... Let's say my
application url is and my application is
hosted at (main being my controller). The
problem is that when I use scaffold my links have the wrong path. For
example, <%= link_to 'Edit', :action => 'edit', :id => torrent %> give
me a link to and not to how can I change this?
