headerValuePF
|
|
=============
|
|
|
|
Description
|
|
-----------
|
|
Calls the specified partial function with the first request header the function is ``isDefinedAt`` and extracts the
|
|
result of calling the function.
|
|
|
|
The ``headerValuePF`` directive is an alternative syntax version of :ref:`-headerValue-java-`.
|
|
|
|
If the function throws an exception the request is rejected with a ``MalformedHeaderRejection``.
|
|
|
|
If the function is not defined for any header the request is rejected as "NotFound".
