Process multiple HTTP requests in parallel without blocking

Although using the conventional LWPUserAgent is fast and easy it does have some drawbacks - the code execution blocks until the request has been completed and it is only possible to process one request at a time. HTTPAsync attempts to address these limitations.

It gives you a ‘Async’ object that you can add requests to, and then get the requests off as they finish. The actual sending and receiving of the requests is abstracted. As soon as you add a request it is transmitted, if there are too many requests in progress at the moment they are queued. There is no concept of starting or stopping - it runs continuously.
