Making cache manifest display properly

Target browsers: cross-browser

As explained in Chapter 6, Mobile Rich Media, cache manifest is used for offline web applications. The extensions for this file may not be recognized by the server. Let's see how we can add the proper MIME type.

Getting ready

Create or open an .htaccess file.

How to do it...

Add the following code:

AddType text/cache-manifest appcache manifest

Upload the .htaccess file to the folder you want the rules to apply.

How it works...

Cache manifest may have either .appcache or .manifest as its extension. By adding both types as text/cache-manifest, we are making sure they can both be rendered correctly regardless of which one is used.

MBP Mobile Boilerplate

The .htaccess rule is included in the Mobile Boilerplate:
