Appcache loading files from browser cache
Circumstances
I'm building a webapp that will be used offline but will also be updated
regularily when it's used online. I'm invalidating the manifest server
side by adding a comment containing a tstamp and then reload the page
automatically via JS as soon as that change is detected. That worked
perfectly fine until now.
Problem
The above process is still executed completely, but for some reason,
everytime the browser tries to fetch the new files, chromes developer
tools tell me it's loaded "from cache" for every file. So only old files
are loaded, changes are ignored.
This occurs even if I deleted the browser cache before. Also, I'm already
using several anti-cache metas and changed IIS's invalidation header for
immediate invalidation.
Additional Info
When I delete the application cache manually the problem is solved. But it
will reoccur after some time (unfortunately i have no idea that triggers
this)
