Help for rewritting without change The URL into browser

[Aitor Iturriondobeitia <laudio.info@xxxxxxxxx>]

I have to rewrite addresses and I can't, see if you can help me.

I have an apache, which calls me with this type of address

http://www.domain.com/food-helps

This internally has to be returned to me by a jboss with, let's say, this url:

http://www.domain.com/32HELP

the problem is that with this:

RewriteRule ^/meal-helps$ /32HELP$1 [L,R]

I get it to redirect me but it also changes the url in the browser and it is necessary that the url in the browser does NOT change

Is it possible with address rewriting that the browser's url is kept and internally rewritten so that it returns the content without changing the browser's url?

Can you help me?

Thank you very much
