Hello Fabian,

regarding the support of HTTP headers, you can have a look at the user 
guide here: http://wiki.restlet.org/docs_2.0/130-restlet.html. The via 
header is not supported yet.
Thus, you will to get the "org.restlet.http.headers" reques's attribute...

I see a problem if the rewriting rule is also based on the path.

Best regards,
Thierry Boileau
