I need the client (using javascript) to invalidate a page it has and essentially fetch a new version?
I thought I could do it all with headers: http://stackoverflow.com/questions/1295397/invalidating-cached-content-if-modified-headers
If there NO way to have the browser refresh its current cached version, with out making a new request (via a new URL) ... so that the same original URL request could be used to see the updated content?
