Check server http resposne and reselect if error, for vhosting

Hello,

 

 

In general, I think you could use a rule to round robin requests to two different nodes. If the load balancing failed or a bad HTTP response code was detected, you could switch to the new node. You would probably want to use a counter to prevent an endless reselect if both nodes are down. After a certain count is reached, you could redirect to an external URL.

 

 

Does your application require persistence? ie, does the app create a session that only exists on one server?

 

 

Do both web servers host identical content?

 

 

Would your client typically be disabling a single vhost to perform maintenance or disabling the web server altogether?
