We have a Web infrastructure with a farm of Web Servers. They are behind a loadbalancer which does SSL offload. We also have a IPS and obviously a set of firewalls.
Now, for security reason we have been asked to look into the possibility of adding a reverse proxy. I insist this is for security reason only as we are not planning to use any caching.
My question is: Is it worth the effort? Is there any added value to an additional layer and if yes would it justify the time spent?
