Is there limit to number of files that can be cached in html5 manifest?

Question

I have lot of.PNG images numbering from 1 to 259 with a total size 250kb. I need these images to be available as thumbnails when the app is used in offline mode. So I created the manifest including all of these resources and then added the manifest to the homepage of the app using the html5 directive but the app failed to run offline. Here is the manifest below;

CACHE MANIFEST
# version 10000

I have used manifest before but with limited number of files which works fine... I don't know why this is failing to work. Is there a way out of this? Any workable solution will be well appreciated. Thank you.

Answer 1

Application cache manifest is deprecated and doesn't work in Chrome 83+

New Web applications should be built around Service Workers. Existing applications that use AppCache should migrate to Service Workers.
