Spell Checking and URL Tricks

this would interest people as well. This is of course a rather useless example.
You can do a lot of quite complex things with the concept presented here.
The ForceType directive
just changes the MIME type of something to the given type, overriding all other settings
for the resource it is applied to. Since it applies to a resource you have to also somehow

<Location> block, but
<Directory> and
<Files> are useful
