%description
Instances of the 'HTTP::Daemon' class are HTTP/1.1 servers that listen on a
socket for incoming requests. The 'HTTP::Daemon' is a subclass of
'IO::Socket::IP', so you can perform socket operations directly on it too.

The accept() method will return when a connection from a client is
available. The returned value will be an 'HTTP::Daemon::ClientConn' object
which is another 'IO::Socket::IP' subclass. Calling the get_request()
method on this object will read data from the client and return an
'HTTP::Request' object. The ClientConn object also provide methods to send
back various responses.

This HTTP daemon does not fork(2) for you. Your application, i.e. the user
of the 'HTTP::Daemon' is responsible for forking if that is desirable. Also
note that the user is responsible for generating responses that conform to
the HTTP/1.1 protocol.

The following methods of 'HTTP::Daemon' are new (or enhanced) relative to
the 'IO::Socket::IP' base class:

* $d = HTTP::Daemon->new

* $d = HTTP::Daemon->new( %opts )

The constructor method takes the same arguments as the 'IO::Socket::IP'
constructor, but unlike its base class it can also be called without any
arguments. The daemon will then set up a listen queue of 5 connections and
allocate some random port number.

A server that wants to bind to some specific address on the standard HTTP
port will be constructed like this:

$d = HTTP::Daemon->new(
           LocalAddr => 'www.thisplace.com',
           LocalPort => 80,
       );

See IO::Socket::IP for a description of other arguments that can be used
configure the daemon during construction.

* $c = $d->accept

* $c = $d->accept( $pkg )

* ($c, $peer_addr) = $d->accept

This method works the same the one provided by the base class, but it
returns an 'HTTP::Daemon::ClientConn' reference by default. If a package
name is provided as argument, then the returned object will be blessed into
the given class. It is probably a good idea to make that class a subclass
of 'HTTP::Daemon::ClientConn'.

The accept method will return 'undef' if timeouts have been enabled and no
connection is made within the given time. The timeout() method is described
in IO::Socket::IP.

In list context both the client object and the peer address will be
returned; see the description of the accept method IO::Socket for details.

* $d->url

Returns a URL string that can be used to access the server root.

* $d->product_tokens

Returns the name that this server will use to identify itself. This is the
string that is sent with the 'Server' response header. The main reason to
have this method is that subclasses can override it if they want to use
another product name.

The default is the string "libwww-perl-daemon/#.##" where "#.##" is
replaced with the version number of this module.

The 'HTTP::Daemon::ClientConn' is a 'IO::Socket::IP' subclass. Instances of
this class are returned by the accept() method of 'HTTP::Daemon'. The
following methods are provided:

* $c->get_request

* $c->get_request( $headers_only )

This method reads data from the client and turns it into an 'HTTP::Request'
object which is returned. It returns 'undef' if reading fails. If it fails,
then the 'HTTP::Daemon::ClientConn' object ($c) should be discarded, and
you should not try call this method again on it. The $c->reason method
might give you some information about why $c->get_request failed.

The get_request() method will normally not return until the whole request
has been received from the client. This might not be what you want if the
request is an upload of a large file (and with chunked transfer encoding
HTTP can even support infinite request messages - uploading live audio for
instance). If you pass a TRUE value as the $headers_only argument, then
get_request() will return immediately after parsing the request headers and
you are responsible for reading the rest of the request content. If you are
going to call $c->get_request again on the same connection you better read
the correct number of bytes.

* $c->read_buffer

* $c->read_buffer( $new_value )

Bytes read by $c->get_request, but not used are placed in the _read
buffer_. The next time $c->get_request is called it will consume the bytes
in this buffer before reading more data from the network connection itself.
The read buffer is invalid after $c->get_request has failed.

If you handle the reading of the request content yourself you need to empty
this buffer before you read more and you need to place unconsumed bytes
here. You also need this buffer if you implement services like _101
Switching Protocols_.

This method always returns the old buffer content and can optionally
replace the buffer content if you pass it an argument.

* $c->reason

When $c->get_request returns 'undef' you can obtain a short string
describing why it happened by calling $c->reason.

* $c->proto_ge( $proto )

Return TRUE if the client announced a protocol with version number greater
or equal to the given argument. The $proto argument can be a string like
"HTTP/1.1" or just "1.1".

* $c->antique_client

Return TRUE if the client speaks the HTTP/0.9 protocol. No status code and
no headers should be returned to such a client. This should be the same as
!$c->proto_ge("HTTP/1.0").

* $c->head_request

Return TRUE if the last request was a 'HEAD' request. No content body must
be generated for these requests.

* $c->force_last_request

Make sure that $c->get_request will not try to read more requests off this
connection. If you generate a response that is not self delimiting, then
you should signal this fact by calling this method.

This attribute is turned on automatically if the client announces protocol
HTTP/1.0 or worse and does not include a "Connection: Keep-Alive" header.
It is also turned on automatically when HTTP/1.1 or better clients send the
"Connection: close" request header.

* $c->send_status_line

* $c->send_status_line( $code )

* $c->send_status_line( $code, $mess )

* $c->send_status_line( $code, $mess, $proto )

Send the status line back to the client. If $code is omitted 200 is
assumed. If $mess is omitted, then a message corresponding to $code is
inserted. If $proto is missing the content of the $HTTP::Daemon::PROTO
variable is used.

* $c->send_crlf

Send the CRLF sequence to the client.

* $c->send_basic_header

* $c->send_basic_header( $code )

* $c->send_basic_header( $code, $mess )

* $c->send_basic_header( $code, $mess, $proto )

Send the status line and the "Date:" and "Server:" headers back to the
client. This header is assumed to be continued and does not end with an
empty CRLF line.

See the description of send_status_line() for the description of the
accepted arguments.

* $c->send_header( $field, $value )

* $c->send_header( $field1, $value1, $field2, $value2, ... )

Send one or more header lines.

* $c->send_response( $res )

Write a 'HTTP::Response' object to the client as a response. We try hard to
make sure that the response is self delimiting so that the connection can
stay persistent for further request/response exchanges.

The content attribute of the 'HTTP::Response' object can be a normal string
or a subroutine reference. If it is a subroutine, then whatever this
callback routine returns is written back to the client as the response
content. The routine will be called until it return an undefined or empty
value. If the client is HTTP/1.1 aware then we will use chunked transfer
encoding for the response.

* $c->send_redirect( $loc )

* $c->send_redirect( $loc, $code )

* $c->send_redirect( $loc, $code, $entity_body )

Send a redirect response back to the client. The location ($loc) can be an
absolute or relative URL. The $code must be one the redirect status codes,
and defaults to "301 Moved Permanently"

* $c->send_error

* $c->send_error( $code )

* $c->send_error( $code, $error_message )

Send an error response back to the client. If the $code is missing a "Bad
Request" error is reported. The $error_message is a string that is
incorporated in the body of the HTML entity body.

* $c->send_file_response( $filename )

Send back a response with the specified $filename as content. If the file
is a directory we try to generate an HTML index of it.

* $c->send_file( $filename )

* $c->send_file( $fd )

Copy the file to the client. The file can be a string (which will be
interpreted as a filename) or a reference to an 'IO::Handle' or glob.

* $c->daemon

Return a reference to the corresponding 'HTTP::Daemon' object.
