Since HTTP typically runs over TCP I assume your concern is not wanting to implement an HTTP server in your app for the P2P functionality? If this is the case, I will first point out that there are actively maintained open source HTTP daemons that I found by Googling (e.g. http://code.google.com/p/cocoahttpserver/); can't vouch for their quality, but seem to be widely referenced and used. It is worth pointing out, with respect to your previous post, that the fact that your servers run Java or the fact that you think XML might be a good file format are not relevant to your decision about lower level network architecture. > However, I have NOT got sufficient materials to program TCP on iPad. Should you decide not to go with NSURLConnection, etc., I would think you should be able to fall back to using NSStream and its siblings before needing to drop all the way down into the CFNetwork layer (which, as others have pointed out, will certainly do what you need without resorting to BSD sockets) for everything. The one subtle complication here is that NSStream does not currently support remote connections on iOS without modification. Fortunately, Apple provides documentation on how to get around this with a minimal amount of CFNetwork to setup the stream: http://developer.apple.com/library/ios/#DOCUMENTATION/Cocoa/Conceptual/Streams/Articles/NetworkStreams.html http://developer.apple.com/library/ios/#qa/qa1652/_index.html This would then give you all the NSStream Objective-C goodness, which comports with the principle of using the highest level constructs available that meet all your needs. (Personally, I would spend a modest amount of time seeing whether I could use HTTP, thereby removing the network stream code entirely. But NSStream isn't too much of a burden if HTTP is unworkable for license, performance, or other reasons.) -- Conrad Shultz Synthetiq Solutions www.synthetiqsolutions.com twitter.com/TechConrad _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
