front end proxy and virtual hosts

[Eric Cholet]

Hi,

The front-end light server, serving static requests and proxying
dynamic requests to a back-end modperl server, is well documented,
except in the case of virtual hosts. How do you do it? Specifically,
do you setup virtual hosts on the backend server? Different IPs, or
different ports? Or just a flat url space, using mod_rewrite on the
front-end to translate the urls?

The modperl guide is sadly lacking any information in this area, so
your input will be valuable.

Thanks,
