port forwarding 2 subdomains & 2 different IPs

Hey,

I was wondering if someone could enlighten me on what possiblities I
might have to do the following:

1 IP from ISP ---> netopia router ---> 2 internal IPS

first internal ip: subdomain for catalog (proprietary library catalog
web server on win2k)
second internal ip: generic website www subdomain running on Apache &
Redhat.

From my understanding of port forwarding, all port 80 requests will go
to one internal IP. If I set it to go to my Apache/Redhat server, can
I set it to forward all the requests for the catalog subdomain to the
proprietary OS/Webserver running on another internal IP?

Cheers,
Daniel

Yes, unless your netopia router is able to make some kind of layer7 magic.

I suggest you use mod_rewrite and configure 2 named based virtual hosts.
The first will simply make a transparent proxy to your catalog, and the
other serve the other domain locally.


Exemple ( may not work ):
<VirtualHost *>
RewriteEngine on

RewriteCond %{SERVER_NAME} "catalog.your.domain"
RewriteRule ^/(.*)$ http://<local ip of catalog server>/$1 [P]
RewriteCond %{SERVER_NAME} "www.your.domain"
RewriteRule ^/(.*)$ $1 [L]
</VirtualHost>

Yes, see apache docs for mod_proxy and ProxyPass. Although, you may want
to get virtual hosting working for the names first with local directories
and when that works, you can switch one to the proxy instead of local
path.

Thanks David and Oliver,

I'll post on how it works out for the library!

Cheers,
Daniel
