IE 10 not using AppCache after browser closed

Question

I wrote an application using the HTML5 Cache Manifest and I'm having a problem using it in IE 10.

I used Fiddler to witness the manifest file being downloaded and all resources fetched on the initial load of the application. If I disable my network adapter to force the machine offline, the application continues to work as expected as long as I don't close the browser window.

However, when I close the browser window, then attempt to re-open the page from a favorite, IE 10 tells me "You're not connected to a network". Obviously I know that, I'm trying to use the app offline. These exact steps work in Chrome.

Is this behavior by design? Is there a workaround? I can't test with IE 11 right now...is this different in IE 11?

Answer 1

Did you find the answer to this? I have the same problem. I did get a bit further though. I found that if you go to the IE10 File menu option and tick Work Offline then try and access your cached app it loads the page but I still have an issue as it does not appear to be using the javascript file that should also be cached. All works ok on Google Chrome but our clients are restricted to IE so Chrome is not an option.

Answer 2

Hearing of some issues of the appcache clearing if your company utilizes gpo settings and has "empty temporary internet files folder when browser is closed" enabled.
