Pool choosing by iRule is wrong, when objects have been named same in different partitions.

Hi Przemyslaw,

I thinks this document explains a bit of the behaviour you are seeing; https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip-system-irules-concepts-11-6-0/4.html (It's from v11.6, but still seems to be relevant)

I suspect it has to do with how iRules are executed as part of the flow of traffic, and as partitions are mainly a form of configuration separation, rather than a resource separation.

In your iRules, I noticed that you only reference the name of the pool (test-case-pool), rather than the partition AND pool name (/fix/test-case-pool) - have you given that a try? that should fix the problem.

Hope this helps.
