Hi Martin,

You can do this with the Apache web server. There are a number of
different features which might do exactly what you want. 

Firstly, Apache can be used to host lots of different sites at once. You
can set up any number of VirtualHosts - these are often found
in /etc/apache2/sites-available/. Each VirtualHost has its own
configuration.

You can use the rewrite module to rewrite the URL to redirect the client
to a different site.

You can use the proxy module to reverse proxy to other servers.

That doesn't really tell you what to do, but I think it gives you a
pointer to where you want to be looking.

very best regards,

Seb James
