[undertow-dev] undertow http client - howto long polling xhr?

[Stuart Douglas]

io.undertow.client.ClientExchange#setResponseListener() lets you set a 
callback that will be invoked once the response headers have been parsed.

You then use the io.undertow.client.ClientExchange#getResponseChannel() 
method to read the body. Because this is an XNIO channel it supports 
async IO via the use of a read listener, which gives you a callback when 
more data arrives.
