Have a single page application that needs to refresh the users browser cache when a newer version is present on the server.

What needs to be done to detect a new version on the server and then what needs to be done in the code to force a refresh?

Thanks.

jquery, Hot Tub, breeze

I suppose you could add an hidden field to the page containing a 'version'
On page load make an ajax request to your server for the current version and if different run

location.reload(true); // same as an hard refresh

Are you using jquery or vanilla javascript?
It would be placed before the closing body tag as you would need for the page to 'load' before you could check if the version field was cached.
