[Directive] JkUnMount [Description] 
An exclusion mount point from a context to a Tomcat worker. All exclusion mounts are checked after mapping a request to a tomcat worker. If the request maps also to an exclusion, it will not be forwarded to tomcat, and instead be served locally. This directive is allowed multiple times. It is allowed in the global configuration and in VirtualHost. You can also use it inside Location with a different syntax. Inside Location, one omits the first argument (path), which gets inherited from the Location. For inheritance rules, see: JkMountCopy. This directive is available in jk1.2.7 version and later.
