This patch adds a check for browser support for the "applicationCache"
feature required by the offline circulation tool. If the feature is not
available, a message is shown to the user that offline circulation is
disabled.
To test, apply the patch and enable the AllowOfflineCirculation system
preference.
In a browser which supports applicationCache (Firefox < 81, Chrome < 94,
Safari <= 15), go to Circulation -> Built-in offline circulation
interface.
- You should see the standard Offline Circulation menu options: Check
out, check in, syncrhonize, etc.
- Click "Synchronize," then "Download records."
- The process should complete correctly, updating the "last synced"
information on the page.
Follow the same steps in a browser which has dropped support for
applicationCache. As soon as you reach the built-in offline circulation
page you should see a message, "Your browser is not compatible..."
