a "proxy" on what level? HTTP/FTP/winsock?
something like a TIS application level HTTP proxy?
or something like a Vixie box that acts more like a filtering router?
(see http://www.mirror-image.com/ for more info)

if the former, I don't think there is anything you can do except
block all HTTP traffic that _DOESN'T_ go to the proxy,
and would require the user to configure the proxy on their browser
or whatever client software that must be aware of the proxy.

if the later, you _can_ configure a connection to use
a specific default route for that connection only (client gateway)
to send all non-local traffic, or specify that all traffic (ip direct)
should be forwarded to a specific router/proxy/server.
