Hi Jason,

That should work find in 10.x. I'd suggest checking that the header value is not null. You should also set a timeout on the persistence record: 

when HTTP_REQUEST { 
   if { [HTTP::header value "X-Nokia-MSISDN"] ne ""} { 
      persist uie [HTTP::header value "X-Nokia-MSISDN"] 3600  
      pool alternate_pool
   }
}

Also, make sure to add a OneConnect profile if you're persistence based on a layer 7 property. If you're using SNAT on the serverside connections, you can use the default OneConnect profile. If you're not using SNAT, then create a custom OneConnect profile with a /32 source mask.
