NAME

       XMLRPC::Transport::HTTP - Server/Client side HTTP support for XMLRPC::Lite

SYNOPSIS

       Client
             use XMLRPC::Lite
               proxy => 'http://localhost/',
             # proxy => 'http://localhost/cgi-bin/xmlrpc.cgi', # local CGI server
             # proxy => 'http://localhost/',                   # local daemon server
             # proxy => 'http://login:password@localhost/cgi-bin/xmlrpc.cgi', # local CGI server with authentication
             ;

             print getStateName(1);

       CGI server
             use XMLRPC::Transport::HTTP;

             my $server = XMLRPC::Transport::HTTP::CGI
               -> dispatch_to('methodName')
               -> handle
             ;

       Daemon server
             use XMLRPC::Transport::HTTP;

             my $daemon = XMLRPC::Transport::HTTP::Daemon
               -> new (LocalPort => 80)
               -> dispatch_to('methodName')
             ;
             print "Contact to XMLRPC server at ", $daemon->url, "\n";
             $daemon->handle;

DESCRIPTION

       This class encapsulates all HTTP related logic for a XMLRPC server, independent of what
       web server it's attached to.  If you want to use this class you should follow simple
       guideline mentioned above.

   PROXY SETTINGS
       You can use any proxy setting you use with LWP::UserAgent modules:

        XMLRPC::Lite->proxy('http://endpoint.server/',
                            proxy => ['http' => 'http://my.proxy.server']);

       or

        $xmlrpc->transport->proxy('http' => 'http://my.proxy.server');

       should specify proxy server for you. And if you use "HTTP_proxy_user" and
       "HTTP_proxy_pass" for proxy authorization SOAP::Lite should know how to handle it
       properly.

   COOKIE-BASED AUTHENTICATION
         use HTTP::Cookies;

         my $cookies = HTTP::Cookies->new(ignore_discard => 1);
           # you may also add 'file' if you want to keep them between sessions

         my $xmlrpc = XMLRPC::Lite->proxy('http://localhost/');
         $xmlrpc->transport->cookie_jar($cookies);

       Cookies will be taken from response and provided for request. You may always add another
       cookie (or extract what you need after response) with HTTP::Cookies interface.

       You may also do it in one line:

         $xmlrpc->proxy('http://localhost/',
                        cookie_jar => HTTP::Cookies->new(ignore_discard => 1));

   COMPRESSION
       XMLRPC::Lite provides you option for enabling compression on wire (for HTTP transport
       only). Both server and client should support this capability, but this logic should be
       absolutely transparent for your application.  Server will respond with encoded message
       only if client can accept it (client sends Accept-Encoding with 'deflate' or '*' values)
       and client has fallback logic, so if server doesn't understand specified encoding
       (Content-Encoding: deflate) and returns proper error code (415 NOT ACCEPTABLE) client will
       repeat the same request not encoded and will store this server in per-session cache, so
       all other requests will go there without encoding.

       Having options on client and server side that let you specify threshold for compression
       you can safely enable this feature on both client and server side.

       Compression will be enabled on client side IF: threshold is specified AND size of current
       message is bigger than threshold AND module Compress::Zlib is available. Client will send
       header 'Accept-Encoding' with value 'deflate' if threshold is specified AND module
       Compress::Zlib is available.

       Server will accept compressed message if module Compress::Zlib is available, and will
       respond with compressed message ONLY IF: threshold is specified AND size of current
       message is bigger than threshold AND module Compress::Zlib is available AND header
       'Accept-Encoding' is presented in request.
