Failover using cache

Hi,

Can any body tell me how to develop a failover between servers using the cache code.

I am creating a website which is furnished by two servers to achieve data availability. I'm just struggling in processing the failover between these servers. I just need the exact code to perform automatic failover.
Condition:
1. If the primary server fails, the secondary server should take the responsibility of theprimary server till it attains its normal.
2. If the primary server resets, the primary server should be automatically take the charge.

It's urgent; Provide me with a failover code...
Thanks

Re: Failover using cache

Shalom,

I would suggest serviceguard, not code, for true reliability.

Concepts:

Use rsync to keep data synched between the active node and the backup node, when people change content.

Direct all web traffic to a floating IP address that moves from node to node depending on which one is active.

Configure a serviceguard package to take care of the above tasks and starting the httpd server on the active node.
