VIP Failover at the web server level??

Question

Oracle10gR2
RHEL 4 AS 64bit
Hi,
I wanted to know is the VIP failover at the web server level also? For example, we are running Apex and that uses Apache/HTTP webserver, if that were to go down on one node, would it failover to the other node? Or is it not at the webserver level?
Thank you.

Yes, thank you for the documentation.
However, I had one question about an action script that is in the following documentation:
http://www.oracle.com/technology/products/database/clustering/pdf/Using_Oracle_Clusterware_to_protect_Oracle_Application_Server.pdf
In there in APPENDIX B is a script called webcache_action.scr. I modified this script to use in our environment to start and stop the http_server process. We have been having some problems with it...mainly when it fails over, it shuts down the http server, then brings it back up, then down again. This is happening in a production system so it's a big issue. My question is can you explain to me why that is happening and maybe also explain what the script is doing? Maybe I'm missing something. Do I even need to have the stop part in the script? All we need to do is when it fails over to startup the http server on the node, that's it! Any help would be appreciated.
