            Description

            If you turn on Resource Coalescing and refresh the page, the ResourceCoalescingHandler appears to detect that there's been no change to the resources and will return an empty response for the CSS and Javascript. If the browser is caching the resource, which will have the same dgt param, then the resource will be fetched from the cache, but if the browser is not caching the resource, CSS and Javascript will be missing.

              Testing Chrome with cache disabled, the browser is sending a no-cache header that the CoalescingResourceHandler could check. If the cache-control header is no-cache, then the handler should increment the digest parameter and resend all of the coalesced resources:
