How can I change the URI when forwarding to a server (no replies)

Hi all,

I wonder if I can change the uri that the server receives without doing
a redirect.

Example:
Request from client: https://www.example.com/login/username?p1=something
Request received by server: /login.php?s=username&p1=something

More general:
- if path begins with /login/*[?*]
- add the first * as a query parameter s to the query
- keep other optional query parameters in place

Is anything like that possible?


Thanks
Jürgen
