I put together a small example of an html5 offline app using cache manifest and deployed it to Heroku:
http://cachemanifest.heroku.com/ I used the clock example from the html5 draft: http://www.whatwg.org/specs/web-apps/current-work/multipage/offline.html Source code: http://github.com/adamwiggins/cachemanifest You can confirm that the manifest is returning the right mimetype like this: $ curl -I http://cachemanifest.heroku.com/clock.manifest HTTP/1.1 200 OK Server: nginx/0.6.39 Date: Thu, 25 Feb 2010 02:53:24 GMT Content-Type: text/cache-manifest ... Visiting the site in firefox 3.5 should ask to allow whether it can store for offline use. Chrome doesn't seem to support this currently, not sure about other browsers.
