HTML5 application cache updating solution

问题

I may get some heat for this question because there are a lot out there already.

BUT... Every question has a different answer and no finite answer seems to be solid.

SO THE QUESTION... If I update a file which is reference in the application cache manifest for an offline available application, how can i force the update of the manifest and the offline cache without changing the manifest?

I hope this is clear. To show that I have done some research:

Updating the cache This requires a change to the manifest though...

Thank you all.

You can't. You must update the manifest file. Be careful to set an immediate expiry header on your manifest file so that the browser recognizes there's been an update to it.
