Synopsis

                  ForceType media-type
directory, .htaccess 

Given a directory full of files of a particular type, ForceType will cause them to be sent as media-type . For instance, you might have a collection of .gif files in the directory .../gifdir, but you have given them the extension .gf2 for reasons of your own. You could include something like this in your Config file:

<Directory <path>/gifdir>
ForceType image/gif
</Directory>

You should be cautious in using this directive, as it may have unexpected results. This directive always overrides any MIME type that the file might usually have because of its extension — so even .html files in this directory, for example, would be served as image/gif.
