Getting the First 10 Characters - iRule Help

[JustCooLpOOLe]

Hi,

I'm taking a session variable and inserting it into a header. Now I want to get the first 10 positions of that session variable. Any ideas on the best approach for this? I know string map and string range are a thing but not sure where that needs to be inserted as so not to break anything.

when ACCESS_ACL_ALLOWED {

 

    HTTP::header insert "THING" [ACCESS::session data get session.logon.last.upn]

 

}

It's working!

when ACCESS_ACL_ALLOWED {
 
    set lastupn [ACCESS::session data get session.logon.last.upn]
    
    HTTP::header insert "THING" [string range $lastupn 0 9]
 
}
