IP address lost in Weblogic proxy plugin

Question

          Hi,
          We have 4 web servers that forward requests for jsps to 10 weblogic instances
          working in a cluster. The web servers have IPlanet with weblogic proxy plugin.
          One of the jsps has logic to retrieve the client's IP address and then return
          the name of the country to which the IP address belongs. But since the jsp always
          receives requests from one of the 4 web servers on the same LAN, it gets only
          the internal IP address of the web server and returns no country code. To retrieve
          the IP address of the caller in the jsp, I'm using
          ipAddress = request.getRemoteAddr();
          How can I make my jsp know the actual source IP address of the client (i.e the
          end user)?
          Any help would be appreciated.

Try increasing the "AcceptBackLog" settings on the weblogic server and then verify for any changed behavior.
Raise the Accept Backlog value from the default by 25 percent. Continue increasing the value by 25 percent until the messages cease to appear.
