How to clear a third-party cache when Craft updates its own template caches We're experimenting with using Fastly for full-site caching of a Craft site. Everything is working great so far, with the exception that Fastly obviously has no way to know when a URL's cache has been invalidated.

We were thinking that the easiest way to make this work would be to use Craft's built-in caching and create a simple plugin that listens for Craft to invalidate a URL's cache (such as when updating an Entry referenced by that cache) and call out to Fastly to clear its cache for the same URL.

Unfortunately, as far as I can tell, Craft doesn't provide an Event for when it updates its own caches. Am I missing something? Any tips on how to go about this?
Can't think of any clever workarounds, but this is on our 2.2 list to add events so that 3rd party services can be notified when template caches get invalidated.
