I’m implementing the HTML 5 offline caching mechanism in the iPhone interface of Turbine and to do that I need to expose a .manifest file. Per the specs, a .manifest file should be served with a content type of text/cache-manifest. I can check this by submitting a HEAD request with curl and the -I switch: ~ >curl http://your-url/sample.manifest -I HTTP/1.1 200 OK Server: nginx/0.7.64 Date: Mon,
