Appcache working in Safari but not Chrome Windows 8.1

I have a webservice running locally (I also tried hosting it on Windows Server). Chrome debugger shows the appcache loading ok and chrome://appcache-internals/ shows the appcache itself.

As my app is using websql the only alternative browser for testing/control purposes available to me was Safari for Windows. The appcache works with this.

When I kill the webservice and reload the page, I get the standard Chrome ERR_CONNECTION_REFUSED error message. Also, under the resources tab in the Chrome debugger, the websql database is gone and the appcache is also gone.

I put my manifest file through a validator and it had no problems there.

Does anyone know if there's anything in particular I need to do?

Thanks in advance

If it is working in Safari but not Chrome this is normally because you have disabled Caching in the DevTools Network panel. If you go back in to DevTools > Network and then on the top row ensure you don't have "Disable Cache" Toggled.
