YSlow is giving us a Grade F on our Umbraco controlled website for "Add Expires Headers"
If I set the Expires: into the far future, will a publish within Umbraco update these files? Or, because the cache means the site will not even request from the server, do I have to change the version numbers of the files to force a reload?
I'm looking to only cache images and stylesheets
I typically configure this in IIS on the folders that contain the media and static files.
I believe it adds a web.config to the directory with the ClientCache configured properly.
