A simple way to unset all variable during Client_CLOSED ?

[danielc]

Hello,

I have a CLOSED_CONNECTION irule at the end of the VS to unset all variables:

when CLIENT_CLOSED {

  TCP::close

  if { [info exists demo1] } {

    unset demo1

  }

  if { [info exists demo2] } {

    unset demo2

  }

,,,,,

 }

However If I have 1000 variable sauy demo1 to demo1000, then I will need to if 1000 times here to unset them, Is there any simple way can unset all variables during CLIENT_CLOSED ? Thanks

Variables are scoped to the connection. After its closed they no longer exist. The only time this is not the case when you create global variables via rule_init. So there is no need to delete these.

Hello Kevin,

Thanks for the answer. Just want to confirm , what you said also apply to " TCP::close " , right?

TCP::close is triggered at the close of the connection. Right after the processing of any iRule events related to that connection, the variables should no longer exist. A connection is a TCP session defined by quatuple of source-ip:source-port and destination-ip:destination-port.
