=head1 DESCRIPTION
This module provides a simple HTTPD for serving simple web application
interfaces. It's completly event based and independend from any event loop
by using the L<AnyEvent> module.
It's HTTP implementation is a bit hacky, so before using this module make sure
it works for you and the expected deployment. Feel free to improve the HTTP
support and send in patches!
The documentation is currently only the source code, but next versions of this
module will be better documented hopefully. See also the C<samples/> directory
in the L<AnyEvent::HTTPD> distribution for basic starting points.
=head1 FEATURES
=over 4
=item * support for GET and POST requests.
=item * support for HTTP 1.0 keep-alive.
=item * processing of C<x-www-form-urlencoded> and C<multipart/form-data> (C<multipart/mixed>) encoded form parameters.
=item * support for streaming responses.
=item * with version 0.8 no more dependend on L<LWP> for L<HTTP::Date>.
=item * (limited) support for SSL
=back
=head1 METHODS
The L<AnyEvent::HTTPD> class inherits directly from
L<AnyEvent::HTTPD::HTTPServer> which inherits the event callback interface from
L<Object::Event>.
Event callbacks can be registered via the L<Object::Event> API (see the
documentation of L<Object::Event> for details).
For a list of available events see below in the I<EVENTS> section.
=over 4
=item B<new (%args)>
This is the constructor for a L<AnyEvent::HTTPD> object.
The C<%args> hash may contain one of these key/value pairs:
=over 4
=item host => $host
The TCP address of the HTTP server will listen on. Usually 0.0.0.0 (the
default), for a public server, or 127.0.0.1 for a local server.
=item port => $port
The TCP port the HTTP server will listen on. If undefined some
free port will be used. You can get it via the C<port> method.
=item ssl => $tls_ctx
If this option is given the server will listen for a SSL/TLS connection on the
configured port. As C<$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.
