Find pool member from cookie

Hi gamm,

 

in case you are using cookie insert as persistence method this article from Debbie describes a method to decode it.

 

Cookie insert works different from universal persistence.

 

Cookie insert does not create table entries. Instead the returning client provides the information with the cookie. That´s why you will get an empty string after looking up the persistence table.

 

With universal persistence the virtual server will parse the real servers (pool members) response and create a table entry with a timeout.

 

The persistence table lookup you are using would return an information about pool, member and port.

 

So you would need to apply a string split to pick the pool member IP address. Did you name the cookie in the persistence profile as described in your request? Just apply Debbie´s iRule with adjusted cookie name to decode it. Please note that the iRule still has to be modified to work in v11.

 

Thanks, Stephan
