I have solved the problem by creating a custom generator based on
ProxyGenerator.java (from Lenya). The generator copies parameters and
headers from the original request to the proxy request, then it copies
cookies and headers back to the response.
This seems to work, with the exception that at least in Forrest, the
ResponseWrapper object passed to the generator via the objectModel map
does not allow modification of response headers and unlike
HttpResponse does not have the setStatus() method (sending Form data
via the POST method often results in a 'page temporary moved' and
redirection to another page). I don't know how to solve this problem -
i.e. dynamic redirection from inside an inner body-*, but this is
perhaps more Forrest specific.

Hi Tal,
you should be able to use {request-param:your parameter}
<map:generate type="html"
src="http://localhost/tr/{1}{2}?{request-param:first}&{request-param:second}&...";>
This will not do as proxy, since there is no knowledge of the query
parameters available to place in the sitemap. Also, above constructs a
query string, which will not be used if the page is to be retrieved
using the POST method.
