+@var{key} must reference a zero-terminated @ascii{}-coded string
+representing the header to look for: it is compared against the
+headers using @cfunction{strcasecmp}, so case is ignored.  A value of
+NULL for @var{key} can be used to lookup 'trailing' values without a
+key, for example if a URI is of the form
+``http://example.com/?trailer'', a @var{key} of NULL can be used to
+access ``tailer" The function returns @mynull{} if no matching item
