In list context both the client object and the peer address will be
returned; see the description of the accept method L<IO::Socket> for
details.
=item $d->url
Returns a URL string that can be used to access the server root.
=item $d->product_tokens
Returns the name that this server will use to identify itself. This
is the string that is sent with the C<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.
=back
The C<HTTP::Daemon::ClientConn> is a C<IO::Socket::INET>
subclass. Instances of this class are returned by the accept() method
of C<HTTP::Daemon>. The following methods are provided:
=over 4
=item $c->get_request
=item $c->get_request( $headers_only )
This method reads data from the client and turns it into an
C<HTTP::Request> object which is returned. It returns C<undef>
if reading fails. If it fails, then the C<HTTP::Daemon::ClientConn>
object ($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.
=item $c->read_buffer
=item $c->read_buffer( $new_value )
Bytes read by $c->get_request, but not used are placed in the I<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 I<101 Switching Protocols>.
This method always returns the old buffer content and can optionally
replace the buffer content if you pass it an argument.
=item $c->reason
When $c->get_request returns C<undef> you can obtain a short string
describing why it happened by calling $c->reason.
=item $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".
=item $c->antique_client
Return TRUE if the client speaks the HTTP/0.9 protocol. No status
code and no headers should be returned to such a client. This should
be the same as !$c->proto_ge("HTTP/1.0").
=item $c->head_request
Return TRUE if the last request was a C<HEAD> request. No content
body must be generated for these requests.
=item $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.
=item $c->send_status_line
