NAME

       Net::EPP::Protocol - Low-level functions useful for both EPP clients and servers.

SYNOPSIS

               #!/usr/bin/perl
               use Net::EPP::Protocol;
               use strict;

               # send a frame down a socket:

               Net::EPP::Protocol->send_frame($socket, $xml);

               # get a frame from a socket:

               my $xml = Net::EPP::Protocol->get_frame($socket);

DESCRIPTION

       This module implements functions that are common to both EPP clients and servers that implement the
       TCP/TLS transport of the Extensible Provisioning Protocol (EPP) <https://www.rfc-editor.org/info/std69>
       as defined in RFC 5734 <https://www.rfc-editor.org/rfc/rfc5734.html>. The only user of this module is
       Net::EPP::Client, but it may be useful if you want to write an EPP server.

VARIABLES

   $Net::EPP::Protocol::THRESHOLD
       At least one EPP server implementation sends an unframed plain text error message when a client connects
       from an unauthorised address. As a result, when the first four bytes of the message are unpacked, the
       client tries to read and allocate a very large amount of memory.

       If the apparent frame length received from a server exceeds the value of $Net::EPP::Protocol::THRESHOLD,
       the get_frame() method will croak.

       The default value is 1GB.

METHODS

               my $xml = Net::EPP::Protocol->get_frame($socket);

       This method reads a frame from the socket and returns a scalar containing the XML. $socket must be an
       IO::Handle or one of its subclasses (ie "IO::Socket::*").

       If the transmission fails for whatever reason, this method will croak(), so be sure to enclose it in an
       eval().

               Net::EPP::Protocol->send_frame($socket, $xml);

       This method prepares an RFC 5734 compliant EPP frame and transmits it to the remote peer. $socket must be
       an IO::Handle or one of its subclasses (ie "IO::Socket::*").

       If the transmission fails for whatever reason, this method will croak(), so be sure to enclose it in an
       eval(). Otherwise, it will return a true value.

               my $frame = Net::EPP::Protocol->prep_frame($xml);

       This method returns the XML frame in "wire format" with the protocol header prepended to it. The return
       value can be printed directly to an open socket, for example:

               print STDOUT Net::EPP::Protocol->prep_frame($frame->toString);
