caching + routing

Newby here!

I have an application that has pages that are translated. Clicking on flags changes the language. That is working nicely, but, for the 'guest' area I would like to cache these pages as they never change. My problem is that the page has the same url for all the languages. I have an action that does this:   def set_lang     set_language(params[:language])     redirect_to(session[:current_page])   end

Then the page renders content based on the language set via set_language.

By using routes is it possible to make the page cacher think the pages are different? Perhaps by appending the current language to the front of the url? (eg /en/controller/action). I am in over my head as far as routing and how to adequately do this.

What I was thinking was this: * default route sends user to /language/guest/welcome * set language redirects to /language/(current page)

Would this work, and if so, how on earth do I code it!

Sorry for the rambling email.... any insight or solutions most most welcome!

Could I perhaps use url rewriting to put a subdomain on each language?

Help!
