Two ways to do this:

1) route traffic from weblogic machine going to port 80, out via DMZ-2
then via DMZ-1. Open your firewalls just for that machine when it
connects out and the response coming back.

2) Install another Squid in DMZ-2, config the weblogic machines squid to
use it as parent for access.
    AND install squid in DMZ-1, config the DMZ-2 squid to use it as
parent for access.
    AND configure each squid down the chain to only allow the weblogic
machines requests out and replies back.

(1) is really the preferred method. Much simpler, thus easily secured,
and it does not involve setting up several copies of new possibly
breachable software just to get one machine web access.
