Cache Clearing files on an origin pull CDN setup

I’ve searched high and low for a plugin to accomplish this, so if i’ve missed it, please point out.

I am in the process of setting up a blog which will be fully cached by a CDN via an origin pull. I am not only doing this for static and media files, but ALL html pages (index, posts, categories, etc).

I want to use origin pull for a few major reasons: fast access to all site files around the world, limit server load since files are primarily served from the CDN, and lastly to protect from server outages since the cached pages are being served. So, if there is another solution that meets these needs, I’m all ears.

If sticking with origin pull, I’ll need a plugin that upon changes to the blog (new posts, editing posts, new comments, etc), will issue a cache clear request to the CDN for all URLs that are affected so that the latest content is viewable on the site. I suspect i’d need to create a plugin that would register for certain actions, and issue a clear when triggered.

Any guidance, or suggestions would be appreciated. Thanks!
