Re: User's language in URL

Great, thanks for your quick reply.

With the introduction of a custom result type, you rely on the Apache 
rewriting. If you want to test the application locally without reverse 
proxy, the redirect will not work. So I rather would go for Apache 
Header edit directive to rewrite the Location header to only loosely 
couple Apache to the Struts application.
