Applicable in ObjectType-class directives.
The force-type function assigns a type to requests that do not already have a MIME type. This is used to specify a default object type.
Make sure that the directive that calls this function comes last in the list of ObjectType directives, so that all other ObjectType directives have a chance to set the MIME type first. If there is more than one ObjectType directive in an object, all of the directives are applied in the order they appear. If a directive sets an attribute and later directives try to set that attribute to something else, the first setting is used and the subsequent ones are ignored.
