I am still working on it, but it thought i got a possible working 
solution using a request based output filter.

If the redirect is done with the "Location" Header it seems to work - 
the output filter is kicked in after the mod_proxy response, i can 
analyze $r->header_out->{Location} and if it matches whatever i want, i 
can do the $r->internal_redirect(uri) which than delivers with some help 
of mod_proxy and mod_rewrite again what i want under the "old request 
url", for things which dont match DECLINED is returned and all is fine.
Any "things" i've missed doing things this way?

Whats not working yet - maybe it wont ever. dont know yet - is the 
scanario where the redirect is done from a .htaccess rule for example 
with "redirect permanent /a /b" (maybe the servlet response.sendRedirect 
wont work too here, still have to try this) - the filter does not get 
called, don't know yet why, but i'll investigating this.

Althoug because the first solution works and i can influence the way the 
redirect is done in my scenario this is a possible way to go. thx for 
your help.
