Description
|
|
-----------
|
|
Transforms the request before it is handled by the inner route.
|
|
|
|
The ``mapRequest`` directive is used as a building block for :ref:`Custom Directives` to transform a request before it
|
|
is handled by the inner route. Changing the ``request.uri`` parameter has no effect on path matching in the inner route
|
|
because the unmatched path is a separate field of the ``RequestContext`` value which is passed into routes. To change
|
|
the unmatched path or other fields of the ``RequestContext`` use the :ref:`-mapRequestContext-` directive.
|
|
|
|
See :ref:`Request Transforming Directives` for an overview of similar directives.
