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/cgibin/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,
"0;
      $daemon->handle;

DESCRIPTION

This class encapsulates all HTTP related logic for a XML
RPC server, independent of what web server it's attached
to. If you want to use this class you should follow sim
ple 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 autho rization 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 be

tween 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 inter face.
You may also do it in one line:: $xmlrpc->proxy('http://localhost/',
cookie_jar => HTTP::Cookies->new(ig

nore_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 '*' val ues) 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 avail able.
Server will accept compressed message if module Com press::Zlib is available, and will respond with compressed message ONLY IF: threshold is specified AND size of cur rent message is bigger than threshold AND module Com press::Zlib is available AND header 'Accept-Encoding' is presented in request.
