* will be thrown triggering an HTTP 301 Permanent Redirect to the same
* URI _with_ a trailing slash. This Exception is caught in the
* `Slim::call` loop. If the route's pattern is defined without a
* trailing slash, and if the current request URI does have a trailing
* slash, the route will not be matched and a 404 Not Found
* response will be sent if no subsequent matching routes are found.
