Sorry, but you know I still don't know exactly what my client want, and I think my client don't even know himself what he wants :)

When I first looked at DeleGate, I tryed to use FTOSV and FFROMCL but I was not able to make them work, perhaps because of the buffering.

Anyway, perhaps there could be an option called for example FURLREWRITE it would work like FTOXX except you would pass something like 'host/user' to the script and it should output something like 'newhost/newuser'. Do you think that could be done (not necessarily by you) ?

Ok, many thanks again. I think I will be able to do anything my client might want with something like this.
