Hi,  
I would like to append “.rss”, straight to my action, ex.  
“/controller/action.rss”. However it seems that I have to use  
“host/action/1.rss” (or another ID-parameter), otherwise I get a routing  
error "No route matches “/controller/action.rss” with {:method=\>:get}

What am I missing?

Thanks!

Add a custom route, something like:

map.connect ‘foo/:rss’,  
:controller =\> ‘foo’,  
:action =\> ‘bar’,  
:requirements =\> { :rss =\> /^[\w]+.rss$/ }
