title: do we need the firewall port open from App server to Webserver
body: <p>we have the below architecture:
  F5 Load Balancer --> Iplanet Web Server --> Weblogic --> Web services(Backend)</p>
  
  <p>The requests to load balancer are routed on port 443 and traffic is routed to Iplanet webserver on port 80.
  The Requests from Iplanet Web server are routed to Weblogic application server on port 7001.
  When a client(Browser) made a request for a jsp page say one.jsp and the response is displayed on browser.
  So the communication happened like this:
  LB:443--> Webserver:80 --> Weblogic:7001</p>
  
  <p>Does weblogic communicate back to web server here to process the request?
  Do we need to open firewall from Weblogic-Iplanet-LoadBalancer(backwards)
  Or the web server just reads the content and displays it?</p>
