Re: Asynchronous HTTP
Async HTTP is based off of AsyncSelect which just sends messages to a
window, and they get processed by some functions for the http, and
then they call you. Not re-entrant the same code that gets run for the
mouse moving or the window resizing is the same kind of code for
asynchttp that you need to write.
