HTTP Monitor not marking nodes down.

No, actually it won't. I have plenty of monitoring to tell me if the server is up and serving http. I use a Cold Fusion page to ensure that Cold Fusion is up and running, we've had issues where CF would crash but the monitors wouldn't care because IIS was still responding to http requests...

The issue I am trying to resolve now is that we are getting errors on our servers that NetIQ is getting a 499 response for and I am trying to find a way to capture that response on our LTM and automatically mark the node down. As it is, NetIQ receives the error, or a customer reports the error, an operator has to manually check which server is effected, call the on call admin and have them remove the node. It takes time and we have no way of knowing how many customers it effects. NetIQ, until recently, wasn't testing the individual web servers just the vip for the web page.
