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

The web-server/dispatchers/dispatch-sequencer module defines a dispatcher constructor that invokes a sequence of dispatchers until one applies.

(make dispatcher ...)  dispatcher/c
  dispatcher : dispatcher/c

Invokes each dispatcher, invoking the next if the first calls next-dispatcher. If no dispatcher applies, then it calls next-dispatcher itself.
