Disable Persistence for Fallback Hosts

Aaron, I have some more questions regarding this:

 

 

-Would you agree that the only possibility to ensure that clients don't get stuck on fallback servers (lower priority group) because of their persistence entry is to solve this with an iRule? Or are there any other ways?

 

 

I'm looking for a general solution to this issue because it's very common in my environment. We have 2 master servers, and if they're not available, we'd like to forward the clients to 1 or 2 fallback servers displaying an outage notice. The problem is if we use persistence for this VS (typically source address persistence), persistent clients still connect to the fallback server although the master servers are available again. Because we often use HTTPS, we cannot use http profiles with fallback urls for that. So I just want the LTM to make sure, that if higher priority servers are available, NO client is forwarded to a low priority server, even if persistence would say something different.

 

 

But I'm really unsure how this is done the most suitable way.

 

 

Hope you can help me once again :-)

 

 

Thanks and regards
