There is a problem between the ProxySG and internal server in a reverse proxy environment where the traffic between them is large and the server load is heavy, but in the same network the load of another internal server is low and traffic between the ProxySG and this server is low also.
There are many causes for this problem. Complete the following steps to determine whether a difference between the Last-modified time in the 200OK responses is causing the ProxySG to not cache the object, making the traffic between the ProxySG and the internal web server larger than it should be.
