Issue seeing session cookie in subsequent requests after being inserted using irule.

Greetings. A vendor requested that we deploy this irule for the purpose of associating connections to the same session so that they can be replayed appropriately with their tool. The irule came from the vendor and has been used by there other customers succesfully. I see the cookies, TLTSID and TLTUID being inserted by the LTM on the response and being received by the client workstation. However, i do not see the TLTSID and TLTUID cookies being sent on subsequent GET requests from the client. Since the TSTSID and TLTUID cookies are not seen in the request, the LTM irule generates and inserts new cookies on the request. I see those new cookies being sent from the LTM to the loadbalanced server(s). However, on the first payload response, the cookies are not present and yet new cookies get generated and inserted on there way back to the client. I made sure the browser is configured to accept all cookies. We also have the LTM insert a session cookie via the LTM cookie persistence profile that we use for persistence. I see that cookie present in http header and it is the same cookie seen in subsequent requests from the client. So it is working appropriately. Any help would be appreciated. thanks! Scott.

when HTTP_REQUEST { if { ([HTTP::cookie exists "TLTSID" ]) } { set tltsid "" } else { binary scan [md5 "[IP::client_addr][TCP::client_port][clock seconds][expr rand()]"] H* hex set tltsid [string toupper $hex] HTTP::cookie insert name "TLTSID" value $tltsid path "/" domain ".tld.com" } if { ([HTTP::cookie exists "TLTUID" ]) } { set tltuid "" } else { binary scan [md5 "[IP::client_addr][TCP::client_port][clock seconds][expr rand()]"] H* hex set tltuid [string toupper $hex] HTTP::cookie insert name "TLTUID" value $tltuid path "/" domain ".tld.com" } }

when HTTP_RESPONSE { if { not ( $tltsid equals "") } { HTTP::cookie insert name "TLTSID" value $tltsid path "/" domain ".tld.com" } if { not ( $tltuid equals "") } { HTTP::cookie insert name "TLTUID" value $tltuid path "/" domain ".tld.com" HTTP::cookie expires "TLTUID" 51840000 relative } }
