Using same LB for servers on multiple subnets

Hi,

Which browser(s) are you seeing the failure on? Can you log the values for the set-cookie headers in the iRule?

If there are multiple JSESSIONID cookies in the request and/or response, which do you want to use? Or do you want to try using all of them?

Also, it would be good to check that the cookie value isn't null before using it for persistence:

when HTTP_RESPONSE {
if { [HTTP::cookie "JSESSIONID"] ne ""} {
persist add uie [HTTP::cookie "JSESSIONID"]
log local0. "[IP::client_addr] Clairmail persistence HTTP_Response. Cookies: [HTTP::header values Cookie]"
}
}
when HTTP_REQUEST {
if { [HTTP::cookie "JSESSIONID"] ne ""} {
persist uie [HTTP::cookie "JSESSIONID"]
log local0. "[IP::client_addr] Clairmail HttpRequest. Set-Cookies: [HTTP::header values Cookie]"
}
}
