persisting on a cookie

Thank you!

 

One more thing..

 

I got this updated iRule:

 

   
 when HTTP_RESPONSE {     
   foreach a_cookie [HTTP::cookie names] {      
     if {$a_cookie starts_with "1234"}{      
       persist add uie [HTTP::cookie "$a_cookie"]      
       log local0.debug "Cookie persist - client IP: [IP::client_addr], Cookie: $a_cookie, Server IP: [IP::server_addr]"     
     } else {     
       persist source_addr 255.255.255.255 3600      
       log local0.debug "Source persist - client IP: [IP::client_addr] , Server IP: [IP::server_addr]"     
       }     
    }     
 }     
 when HTTP_REQUEST {     
   foreach a_cookie [HTTP::cookie names] {      
      if {$a_cookie starts_with "1234"}{      
        persist uie [HTTP::cookie "a_cookie"]      
        log local0.debug "Client IP: [IP::client_addr], Cookie value: $a_cookie"     
       }      
    }      
 }    
 

 

I would like to persist on a cookie which starts with 1234, but if it's not available I need to run source IP persistence.

 

I already set this up in the HTTP_RESPONSE but I just wonder how to enable it on a VS is my primary persistence will be set to Universal.

 

If the fallback persistence will work in this example or I need to add more code looking up the persistence table for this IP?
