RE: Reverse proxy ??

Hello:

 I have to humbly disagree with Eric's definition of what Reverse Poxy is.
His definition actually describes what I would call HTTP acceleration or
on-command caching. "In on-command caching, the proxy server is setup to
automatically retrieve certain pages, or entire sites, at regular intervals."1

Reverse Proxy: Reverse proxy caching acts as a front end to publishing
servers. In the reverse proxy scenario, the reverse proxy server acts as a
proxy for the server, the proxy services requests on behalf of the server.
