Typically I'd like to know if it's possible to have a setup where it maps some IPs with a particular proxy and other IPs using another proxy?

Proxy Chaining isn't really what I'm looking for (well I don't think it is) because each address could be resolved with or without a proxy but their content may not be accessible without the right proxy.

This setup could be part of home network, so that the relevant proxy s/w could be installed and setup on a Linux box for ex.

Ex:

• website-A via proxy-1
• website-B via proxy-2
• all others via no-proxy
