Hi,

 

you can do it with a simpler code:

 

when HTTP_REQUEST {
    set parameters [findstr [HTTP::path] ";" 1]
    foreach parameter [split $parameters ";"] {
        scan $parameter {%[^=]=%s} name value
        if {$name equals "jsessionid"} {set session_id $value}
    }
    if {$session_id ne ""}{
            Persist on the parsed session ID for X seconds
            if {$debug}{log local0.debug "$logTuple :: Single JsessionID in: [HTTP::host][HTTP::uri]"}
            persist uie $session_id 86400
    }
}
