Irule to insert SNI based on Pool member

This is based purely on this link CloudDocs Wiki: LB::Server and an server ssl profile irule I saw a year back, but forgot the source of. I do not have any experience with this irule, nor have I tested it.

You could create multiple server ssl profiles each with it's own Server Name value.

when LB_SELECTED {
    log local0. "LB_SELECTED: Connected to [LB::server name] [LB::server addr]"
 
    switch [LB::server name] {
        "abcd.domain.local" { SSL::profile abcd_serverssl }
        "efgh.domain.local"  { SSL::profile efgh_serverssl }
  }
 

It is possible that the SSL::profile command can't be utilised in the LB_SELCTED event, in which case you'll have to move it to SERVER_CONNECTED (which is where the example I saw used it).
