I would like to check a url segment (in this case whether the site is  
/en/ or /zh/) so I can display content based on language.

In Radiant what is the quickest and least expensive way to do this?

Thanks!

The \<r:if\_url\> and \<r:unless\_url\> tags probably provide what you need.  
Give the tags a ‘matches’ attribute that contains a regular expression.  
Here’s an example:

\<r:if\_url matches="^/en/"\>\<r:content part=“body\_en” /\>\</r:if\_url\>

That would output the “body\_en” part if the beginning of the URL matches  
/en/.

Doh. That was sitting right in front of my face. Thanks for the quick  
reply, Sean!
