Re: Introduction and first questions



Steve,

I do this with a reverse proxy server.

All web hits go to a single server, which then uses virtual hosts to work
out which machine was actually being asked for the pages.

Personally, I use Apache2 to do this (on Windows 2000).

The key conceptual issue is that while PACKETS are routed to a specific
machine based on IP address, the HTTP REQUESTS inside those packets ask for
a particular page including the server name.... and that one given machine
can be responsible for many different server names (virtual hosting.)

You then tell some of these virtual hosts to forward the HTTP requests on
(unbeknownst to the requesting client) and chuck back the response.

so requests to http://bibble.ascentium.co.uk and
requests to
http://bobble.ascentium.co.uk
go to the same server as far as the Internet's
concerned, but that server sends them on internally within my LAN and
passes
back the response.

Let me know if you want a sample apache configuration file that shows
this...

M.
