Thanks everybody for your suggestions. I actually went through the past
threads on that topic, and it seems to me it always sparks much
discussion!!

Exactly.

I actually use some caching, so I don't expect to have much penalties from
it.
I finally decided to rewrite the URI translation handler in perl
at first, and later on directly in C for best performance. This approach
will also allow me to tune the translation stage to my particular case
and remove all the little inefficiencies (extra stat()'s) there.
As opposed to your case I don't have downstream frontpage or CGI, so I
guess I don't need to worry about passing along the DOCUMENT_ROOT correctly.
Though as you say it would be nice to simplify the whole process in
the future.
Cheers,
Serge
