Persistence on value present in one of 3 places

Hello!  Looking to force persistence on a single value found in either the URI of a request, in a header (present in a header but is not the header itself) or the payload. When a request is r...

Hello! 

Thank you for this. This works really well and logs the value for each of the 3 parts. From the screenshot below you can see the results of this:

Something however wasn't working well and some transactions were failing and this I believe is due to the request not "persisting" and being sent to the other Pool Member. (the setup is testing a round robin accross 2 seprate servers) 

I then added the LB_SELECTED LB::SERVER to see exactly where this traffic is going to and it seems as though the logging of LB::SERVER isn't really logging each HTTP request. Each transaction / connection attempts generates multiple requests as you can see from the above yet for some requests the server is only logged once. 

 

I then decided to use BIG IQ and can see that some are being sent to the wrong pool member and I have no idea why. I can see the reference is present in the header or payload and is always there.

 

Some requests don't even log the Pool Member;

I'm also unable to get the LB::enable_decisionlog working to see the logic behind choosing said pool member.
