Persistence based on IMAP-User

 
 when CLIENT_ACCEPTED { 
  
    Clear the variable imap_login if it exists already on this TCP connection    
       if {[info exists imap_login]}{    
          unset imap_login    
       }    
       Define STREAM-expression and enable STREAM 
          STREAM::expression @LOGIN\.*@ 
          STREAM::enable    
        
           Enable the STREAM_MATCHED event as it could have been disabled if there was a prior     
           response on this TCP connection    
          event STREAM_MATCHED enable    
    
    }    
    when STREAM_MATCHED {    
        
       Save the matched value     
      set imap_login [getfield [STREAM::match] " " 2] 
   
   Check if $imap_login isn't empty  
  if { $imap_login != "" }{  
  
    $imap_login isn't empty...so let's continue 
    log local0. "IMAP Login Information found...continuing"   
  
           The iRule parser doesn't allow the persist command in STREAM_MATCHED.      
           It works though, so hide the command from the parser    
          set persist_cmd "persist add uie $imap_login" 
           log local0. "[IP::client_addr]:[TCP::client_port]: Parsed: $imap_login \$persist_cmd: $persist_cmd"    
        
          eval $persist_cmd 
          persist add uie $imap_login 
  
           log local0. "[IP::client_addr]:[TCP::client_port]: Added persistence record for $imap_login on server [IP::server_addr]:[TCP::server_port]. Exiting event for this response."    
          event STREAM_MATCHED disable    
      } else { 
     $imap_login is empty...let's stop this here  
     log local0. "no IMAP Login Information found...aborting"   
       
  }    
    } 
 

I tried to include it as a universal persistence profile into the VIP

and I simply addes the iRule to the VIP.

But there was no difference.

Is it possible that it doesn't work because of the " " around the user@domain.com ?

Some more debug logging would be great!

Thanks in advance!
