Net::Async::HTTP implements an asynchronous HTTP user agent. It sends requests to servers, returning Future instances to yield responses when they are received. The object supports multiple concurrent connections to servers, and allows multiple requests in the pipeline to any one connection. Normally, only one such object will be needed per program to support any number of requests. As well as using futures the module also supports a callback-based interface. Net::Async::HTTP optionally supports SSL connections, if IO::Async::SSL is installed. If so, SSL can be requested either by passing a URI with the https scheme, or by passing a true value as the SSL parameter. WWW: http://search.cpan.org/dist/Net-Async-HTTP/
