About 3 years ago, we paid to have our system upgraded by your team. A new server was added with a newer version. We have noticed that the new server when we edit via the designer makes calls to various CacheControl.asx pages on the previous server. The specfic ones are /Runtime/CacheControl.ashx, /Management/CacheControl.ashx and /Designer/CacheControl.ashx. We confirmed that we are NOT setup as a farm but as a single instance. I reviewed most of the web.config files and cannot find a reference to the other machine anywhere. Is there something that got missed in the upgrade and how can we stop the new machine from trying to hit this old machine as we would like to retire that old server.
