Date Tue, 16 Nov 2010 16:22:14 GMT

Oleg Kalnichevski commented on HTTPCLIENT-973:

> I would need some assistance regarding the design of how it would integrate with the
rest of HttpClient.

Hi John

I am far from being a fan of (mis)using of NIO just for the heck of it, but in case of the
WebSocket protocol I think that a non-blocking I/O model would make good sense. So, you should
start off by taking a look at HttpCore NIO to get a feel for developing asynchronous services
based on HttpCore [1]. There is also an asynchronous version of HttpClient at a very early
(pre-alpha) stage of development that you might find useful, as it has an implementation of
a pooling connection manager for non-blocking HTTP connections [2]

>             Project: HttpComponents HttpClient
>          Issue Type: New Feature
>          Components: HttpClient
>            Reporter: Erik Martino Hansen
>             Fix For: Future
> Websocket are designed for browser use but I see useful use cases in a java client as
> - java clients for existing websites where changes are pushed to clients using websockets
> - use of websockets to tunnel through firewalls
> - put all communication behind single port on servlet engine.
> A good example on emerging use is websocket+stomp (http://jmesnil.net/stomp-websocket/doc/,
> so I believe hc should support websocket clients.
