UIE string based persistence help

Thanks for the helpful tips

I haven't tried removing the second persist command so that is something I can easily try and report back.

Also I will try the persist add on the 1st socket and then simply the persist command on the second.

I only recently added the LB_SELECTED event because a dev central article recommended, here is an excerpt from that:

To add a record to the persistence table, run the “persist add” command after the persistence token can be associated with the persistence target. (LB_SELECTED is the first event in the serverside request context, and would be a logical place to run the command).
