I am looking at setting up an app server running an HR application. I want employees to be able to access it from home and internally at work. One option is to set up two app servers one internally and one externally outside the firewall. Another option someone suggested was to just set up some kind of external apache server that just redirects traffic to the internal app server through an open port in the firewall. I'm not sure what is best or what is most secure. I have a lot of reading to do. Can anyone advise on the pros and cons or suggest some good reading material? I will be using the most recent version of weblogic. Thanks.
