configured port. As C<$tls_ctx> you can pass anything that you can pass as
C<tls_ctx> to an L<AnyEvent::Handle> object.

Example:

   my $httpd =
      AnyEvent::HTTPD->new (
         port => 443,
         ssl  => { cert_file => "/path/to/my/server_cert_and_key.pem" }
      );

Or:

   my $httpd =
      AnyEvent::HTTPD->new (
         port => 443,
         ssl  => AnyEvent::TLS->new (...),
      );

=item request_timeout => $seconds

This will set the request timeout for connections.
The default value is 60 seconds.

=item backlog => $int

The backlog argument defines the maximum length the queue of pending
connections may grow to.  The real maximum queue length will be 1.5 times more
than the value specified in the backlog argument.

See also C<man 2 listen>.

By default will be set by L<AnyEvent::Socket>C<::tcp_server> to C<128>.

=item connection_class => $class

This is a special parameter that you can use to pass your own connection class
to L<AnyEvent::HTTPD::HTTPServer>.  This is only of interest to you if you plan
to subclass L<AnyEvent::HTTPD::HTTPConnection>.

=item request_class => $class

This is a special parameter that you can use to pass your own request class
to L<AnyEvent::HTTPD>.  This is only of interest to you if you plan
to subclass L<AnyEvent::HTTPD::Request>.

=item allowed_methods => $arrayref

This parameter sets the allowed HTTP methods for requests, defaulting to GET,
HEAD and POST.  Each request received is matched against this list, and a
'501 not implemented' is returned if no match is found.  Requests using
disallowed handlers will never trigger callbacks.
