It should work fine, we do something very similar.  The trick is that
after the prepare_path fixup (if you did it like in the wiki), when you
stringify c.req.uri, it will reflect the *new* base, not the original. 
Using your example:

   original request url:    http://www.site.com/prg?var1=val1&var2=val2
   rewritten request url:  
   http://www.site.com/en/prg?var1=val1&var2=val2

So you should have:

   [%
      uri  = c.req.uri;     #
      http://www.site.com/en/prg?var1=val1&var2=val2
      base = c.req.base;    # http://www.site.com/en/

      pattern = '^' _ base;                        # pattern not
      tested...
      path_and_query = uri.replace(pattern, '');
   %]

So it's easy to strip "base" from the front of "uri" and get what you
need, without knowing what "base" is.

This could work, but given the same original url and prepare_path fixup,
you will have:

   [%
      uri = c.req.uri;                         #
      http://www.site.com/en/prg?var1=val1&var2=val2
      path_and_query = c.req.uri.path_query;   #                   
      /en/prg?var1=val1&var2=val2
   %]

So now when you build the new url you have to be aware that
path_and_query contains the "/en" part that needs to be stripped.
