Re: Catching a list of variables with a Controller

This works for me:

   class Filter < R '/filter/([\w/]+)'
     def get tags
       @tags = tags.split('/')
     end
   end

Then http://localhost:3301/filter/tag1/tag2/tag3 will make @tags into  
['tag1', 'tag2', 'tag3']. I think this is what you want...
