#### 2.6`` Filtering Requests

( require web-server/dispatchers/dispatch-filter )

The web-server/dispatchers/dispatch-filter module defines a dispatcher constructor that calls an underlying dispatcher with all requests that pass a predicate.

( make regex inner) → dispatcher/c
regex : regexp?
inner : dispatcher/c

Calls inner if the URL path of the request, converted to a string, matches regex. Otherwise, calls next-dispatcher.
