i'm reading through Dive into HTML5: Offline web applications: Cache manifest
... but it should be offered using the content type text/cache-manifest. If you're running an Apache-based web server, you are able to most likely just put an AddType directive within the .htaccess file at the bottom of the web directory
AddType text/cache-manifest .manifest
basically dont add this what's going to happen? may be the content type essential? used to do searching for
httpd.conf. however i dont see
content-type for say
images etc. it dont appear everything important in the end?
The chances are without having this content type set properly the browsers will not address it like a manifest file, like the well-known Opera problem where stylesheets get overlooked if offered having a plain text MIME type.
This content kinds of your Apache server are possibly not in httpd.conf, they're usually saved in another configuration file mime.types (automatically, though it may be transformed).
