Paulius For example: I have the following irule

when HTTP_REQUEST {
    # Check if we have already deleted the cookies
    if {not [HTTP::cookie exists tracking_cookie]} {
        # Define an array of cookie names to delete
        set cookie_names [list "loadedFromBrowserCache" "_gid" "_ga" "GuysOnlineFilter" "CruisingListingsFilter" "notifycached"]
        # Loop through each cookie name and delete it if it exists in the ".squirt.org" domain
        foreach cookie_name $cookie_names {
            set CookieDomain [HTTP::cookie domain ${cookie_name}]
            log local0. "Domain name is : ${CookieDomain}"
            if {[HTTP::cookie exists ${cookie_name}] and ${CookieDomain} contains ".sq.org"} {
                HTTP::cookie remove ${cookie_name} domain ".sq.org"
            }
        }
        # Set the tracking cookie to ensure we only delete the cookies once
        HTTP::cookie insert name tracking_cookie value "true" domain ".sq.org"
        HTTP::cookie attribute dummy_cookie value "expires" "Sun, 26-Feb-2023 00:00:00 GMT"
        #HTTP::cookie expires tracking_cookie "1676476831"
    }
}

 

In the tmm log I see the variable as empty

    rajb What happens if you add the following just before you "Domain name is:" logging line?

                log local0. "Cookie name is: ${cookie_name}"

        rajb Try out this iRule and internal data-group to see if it works for you.

         

        when HTTP_REQUEST priority 500 {

    # Check if we have already deleted the cookies
    log local0. "Running within HTTP_REQUEST"

    if {![HTTP::cookie exists tracking_cookie]} {

        log local0. "Running within tracking_cookie"

        foreach a_cookie [HTTP::cookie names] {

            # Compares the cookie name to the internal data-group list called CLASS-CookieList
            if { [class match -- [HTTP::cookie name ${a_cookie}] == CLASS-CookieList] } {

                set CookieDomain [HTTP::cookie domain ${a_cookie}]

                log local0. "Executing cookie: ${a_cookie}"
                log local0. "Domain name is: ${CookieDomain}"

            }

        }

    }

}

         

        The following data-group can be loaded into your configuration by using "load sys config from-terminal merge" without the quotations. You will see a prompt that shows you the key sequence to press to commit the change you are loading in. Make sure it is the exact command less the quotation marks.

         

        ltm data-group internal CLASS-CookieList {
    records {
        CruisingListingsFilter { }
        GuysOnlineFilter { }
        _ga { }
        _gid { }
        loadedFromBrowserCache { }
        notifycached { }
    }
    type string
}

         

        I am interested in knowing what the logs show after using this iRule if you can parse the logs for your iRule name which seems to be called "delete_cookie_test" on your F5.

      Paulius This the updated irule and the output

      when HTTP_REQUEST {
    # Check if we have already deleted the cookies
    log local0. "Running within HTTP_REQUEST"
    if {not [HTTP::cookie exists tracking_cookie]} {
        log local0. "Running within tracking_cookie"
        # Define an array of cookie names to delete
        set cookie_names [list "loadedFromBrowserCache" "_gid" "_ga" "GuysOnlineFilter" "CruisingListingsFilter" "notifycached"]

        foreach cookie_name $cookie_names {
            set cookieDomain [HTTP::cookie domain "${cookie_name}"]
            log local0. "Executing cookie: ${cookie_name}"
            log local0. "Domain name is: ${cookieDomain}"
  
        }
    }
}
