Rewrite Help

Hi,

I am what Nginx and regex concerns still very inexperienced.

Hopefully you can help me.

Nginx is used as a reverse proxy.

The following should be implemented.

Current Url
-> Http://www.example.de/web/user1
should look like this:
-> Http://www.example.de

and
-> Http://www.example.de/web/oranisation
should look like this:
-> Http://www.example.de/oranisation.

Greetings
OSC
