Hello Benoit,

 

"event disable all" it is necessary? do you have others irule who uses the same event on the same vs?

 

because the risk that there may be, if you are redirecting the client back to the same virtual server, you may face situations where the client uses the same connection. This in turn means no further events will be executed, because of disabling all events for that given connection.

 

and therefore your restriction does not work...
