SYNOPSIS

12               proxy => 'http://localhost/',
13             # proxy => 'http://localhost/cgi-bin/xmlrpc.cgi', # local CGI server
14             # proxy => 'http://localhost/',                   # local daemon server
15             # proxy => 'http://login:password@localhost/cgi-bin/xmlrpc.cgi', # local CGI server with authentication

DESCRIPTION

39       This class encapsulates all HTTP related logic for a XMLRPC server,
40       independent of what web server it's attached to.  If you want to use
41       this class you should follow simple guideline mentioned above.
42
43       PROXY SETTINGS
44
45       You can use any proxy setting you use with LWP::UserAgent modules:
46
47        XMLRPC::Lite->proxy('http://endpoint.server/',
48                            proxy => ['http' => 'http://my.proxy.server']);
49
50       or
51
52        $xmlrpc->transport->proxy('http' => 'http://my.proxy.server');
53
54       should specify proxy server for you. And if you use "HTTP_proxy_user"
55       and "HTTP_proxy_pass" for proxy authorization SOAP::Lite should know
56       how to handle it properly.
57
58       COOKIE-BASED AUTHENTICATION
59
60         use HTTP::Cookies;
61
62         my $cookies = HTTP::Cookies->new(ignore_discard => 1);
63           # you may also add 'file' if you want to keep them between sessions
64
65         my $xmlrpc = XMLRPC::Lite->proxy('http://localhost/');
66         $xmlrpc->transport->cookie_jar($cookies);
67
68       Cookies will be taken from response and provided for request. You may
69       always add another cookie (or extract what you need after response)
70       with HTTP::Cookies interface.
71
72       You may also do it in one line:
73
74         $xmlrpc->proxy('http://localhost/',
75                        cookie_jar => HTTP::Cookies->new(ignore_discard => 1));
76
77       COMPRESSION
78
79       XMLRPC::Lite provides you option for enabling compression on wire (for
80       HTTP transport only). Both server and client should support this capa‐
81       bility, but this logic should be absolutely transparent for your appli‐
82       cation.  Server will respond with encoded message only if client can
83       accept it (client sends Accept-Encoding with 'deflate' or '*' values)
84       and client has fallback logic, so if server doesn't understand speci‐
85       fied encoding (Content-Encoding: deflate) and returns proper error code
86       (415 NOT ACCEPTABLE) client will repeat the same request not encoded
87       and will store this server in per-session cache, so all other requests
88       will go there without encoding.
89
90       Having options on client and server side that let you specify threshold
91       for compression you can safely enable this feature on both client and
92       server side.
93
94       Compression will be enabled on client side IF: threshold is specified
95       AND size of current message is bigger than threshold AND module Com‐
96       press::Zlib is available. Client will send header 'Accept-Encoding'
97       with value 'deflate' if threshold is specified AND module Com‐
98       press::Zlib is available.
99
100       Server will accept compressed message if module Compress::Zlib is
101       available, and will respond with compressed message ONLY IF: threshold
102       is specified AND size of current message is bigger than threshold AND
103       module Compress::Zlib is available AND header 'Accept-Encoding' is pre‐
104       sented in request.
