cache-control affect the behavior of updating offline cached resources in chrome.

[neekey]

I test application offline features in chrome ( by now , it's 30 ), and what made me confused is that after change my manifest , event the application cache events go well ( checking, downloading, updateready..), but the resources still not update( after I refresh the page again ). However I have done lots of experiments, and it turn out that it is caused by the cache-control.

For example, if cache-control set to max-age:20, then during this 20sec, if I update my manifest file, the page will reloading all the resources within the list, but all the downloading process just use the browser cache( not offline cache, just browser cache created by cache-control ), which means your resources will not be updated even u update your manifest.

And this problem just happen to Chrome Desktop version, all the mobile version I have tested just work well.

Just wonder if anyone else also had found this issue?
