A client just ran their site through a free SEO audit and let us know that some JavaScript in App_Plugins wasn't being compressed (we have dynamic and static compression enabled server-wide). It's an older site running on Umbraco 7 but the client hasn't been willing to let us rebuild it yet and I noticed that Umbraco 8 is adding the same rule excluding App_Plugins from compression. Does anyone have some insight into why this might be? I commented that out on this site and it appears to be working correctly. I could only think of some caching situations that might be a cause for this rule. Am I missing something?
