Create N virtual hosts in Apache, each running on a specific ipaddress. Use mod_proxy + mod_rewrite with [P] directives on each to give you the dynamic proxying.
Could you give an example ? As far as I can tell, mod_proxy uses static config lines - how do you make that dynamic based on what the client browser enters in the URL field of the base page ? See below ...

Secondary proxy ?
Let's say we have a really simple system set up, with 3 IP addresses :
eth0:1 is 10.0.1.1
eth0:2 is 10.0.2.1
eth0:3 is 10.0.3.1
I want a very simple basic page, with a pulldown list of the 3 IP addresses/interfaces, and an entry box to enter in a URL. The client browser selects eth0:1/10.0.1.1 and enters http://www.mydomain.com/testing into the entry field (could be any URL - that's key).
Apache then fetches http://www.mydomain.com/testing using 10.0.1.1 as the source IP address and presents back up to the client browser. mydomain.com thinks that the browser is actually coming from 10.0.1.1.

NAME
pactester - Tool to test proxy auto-config (pac) files.
SYNOPSIS
pactester <-p pacfile> <-u url> [-h host] [-c client_ip] [-e]
pactester <-p pacfile> <-f urlslist> [-c client_ip] [-e]
DESCRIPTION
pactester is a tool to test proxy auto-config (pac) files. It returns the proxy config string for the given URL and the pac file. pactester
uses pacparser C library for most of its functionality.
OPTIONS
-p pacfile
PAC file to test. Specify "-" to read from the standard input.
-u url URL to test the PAC file for.
-h host
Host part of the URL. If not specified, it's determined from the URL.
-c client_ip
Client's IP address (as returned by the function myIpAddress() in PAC files). If not specified, it defaults to the IP address of
the machine on which this tool is running.
-e Enable Microsoft PAC extensions (dnsResolveEx, myIpAddressEx, isResolvableEx).
-f urlslist
A file containing the list of URLs to be tested. This is good for testing a PAC file against a set of URLs.
EXAMPLES
To find out the proxy config string for the pac file "wpad.dat" and the URL "http://www.google.com":
$ pactester -p wpad.dat -u http://www.google.com
For a client with IP address 10.0.12.123:
$ pactester -p wpad.dat -c 10.0.12.123 -u http://www.google.com
For a pac file hosted at http://wpad/wpad.dat:
$ curl -s http://wpad/wpad.dat | pactester -p - -u http://google.com
