6 JSON::RPC - Perl implementation of JSON-RPC 1.1 protocol
7
9 JSON-RPC is a stateless and light-weight remote procedure call (RPC)
10 protocol for inter-networking applications over HTTP. It uses JSON
11 as the data format for of all facets of a remote procedure call,
12 including all application data carried in parameters.

16 This module was in JSON package on CPAN before. Now its interfaces was
17 completely changed.
18
19 The old modules - JSONRPC::Transport::HTTP and Apache::JSONRPC are
20 deprecated. Please try to use JSON::RPC::Server and JSON::RPC::Client
21 which support both JSON-RPC protocol version 1.1 and 1.0.
