HTTP forward to Pool not working as expected

Hi Chris

 

 

thanks for your reply and yes that is making more sense to me now. I have edited the iRule to set the default pool when the client accept event is triggered.

 

 

In answer to your question OneConnect is not turned on but we use a Cookie Hash Default Persistence and a source_addr Fallback Persistence Profile.

 

 

I guess that explains what I am seeing below. I ran three tests in succession to test the failover and fail back between the pools.

 

 

The first two tests operate as expected however the third test established a connection to the sorry server and maintains that connection even though the iRule is directing it to the default pool. You can see that there is no event for the third test.

 

 

Is persistence the cause of this? Is there someway to alter the behavior of the connections when they are being diverted to the sorry server pool?

 

 

Thanks

 

 

Paul
