I am new to linux and am trying to learn by solving a real problem
I work for a company that hosts web based applications written in house. We host these on our own servers in colo racks a number of data centers.
We are having to move some servers from one data center to another thus forcing a change to the public facing IP address of that server as the two data centers are owned by different companied and we have different ip ranges at each.
In order to achieve a smooth transition for the clients on these servers I thought about using a debian based proxy server to take in requests from the internet to www.xyz.com
on the original IP address 18.104.22.168 and then point them to the server that has moved but still has the www.xyz.com
site and is now on IP 456.456.456.456
I think I can do this using apache and the mod_proxy feature. I have been playing around a bit with this all day with little success. I feel I am on the right track but hoped somebody could tell me that my plan is possible and give me some pointers.
I think it will involve editing the httpd.conf, possible the modules.conf and maybe I need an extra module that is not standard.Any advise gladly received.
I am using a Debian distro and have Apache 1.3.xx running.
