Adding MIME Types

When a Document or Static Resource is stored on the server, the appropriate MIME type must be specified when the file is sent to the user's browser, so the browser knows what to do with that file. Normally, that process happens automatically: The most common file extensions are already recognized by the platform, and the file extension determines which MIME type is specified.

When a file has an extension that the platform does not recognize, however, the file may be mishandled when it reaches the browser. That problem can be solved by adding a line to the configuration file.

In {apache_install_dir}/conf/httpd.conf, add:

AddType  MIME_TYPE  FILE_EXTENSION

For example, to configure an HTML5 cache file with extension .appcache, add the following:

AddType  text/cache-manifest  .appcache
