The idea being listed stems from my work on the WebKit browser. In WebCore,
various "network" backend implementations exist, including a cURL backend. No
other port uses the cURL backend anymore, except for Haiku, as far as I am
aware. The advantage of the other ports is a much more fine-grained control
over network requests. Maybe it is possible to achieve the same with cURL,
but it may or may not need a lot of work to overcome some current limitations
like missing asynchronous requests and perhaps more. Unfortunately I haven't
looked deeply into the issue. The networking backends of the other port are
probably a good example of what is needed. Ryan mentioned the Chromium
backend, personally I've only looked at the Qt backend. Both backends also
offer transparent local caching of network data. I suppose the Qt framework
is a good design and the Haiku class framework should be similar. Maybe the
Chromium design is even better. The first task is to look at the requirements
of the web browser and other networked applications and digest the existing
frameworks to destill the best design.
Best regards,
