Hi

Turned out there isn't an easy way to configure SSL offloading for Tomcat or at least I don't know any. So I updated the iRule as follows.

when HTTP_REQUEST {
  if { [HTTP::uri] starts_with "/foo" } {
     pool foo
  } else {
     pool bar
 }
}

when HTTP_RESPONSE {
   if { [HTTP::status] contains "302" && [HTTP::header Location] contains "http://" && [HTTP::header Location] contains "/foo" }{
      HTTP::header replace Location [string map -nocase {"http://" "https://"} [HTTP::header Location]]
   }
}
