(handle-request selector extra) procedure
(request selector matches extra) record
handlers parameter

handle-request is the primary handler procedure, suitable for passing to gopher#accept.

It executes the handlers in (handlers) in order until one returns a true value. If a handler throws an exception, processing terminates immediately, a generic internal server error is sent to the user, the error is logged, and the exception is re-signaled.

Each handler is passed a request record. The selector and extra fields are taken directly from the arguments to handle-request (see gopher#accept for an explanation). The matches field is initially the empty list, but may be modified by the matcher procedures, which perform a regex match on the selector and set matches to the submatch results.
