This email sent to site_archiver@lists.apple.com I don't have specific ideas, but have you tried troubleshooting by sniffing the HTTP/DAV traffic generated by the request? I generally use the 'tcpflow' command for this (not built-in, but you can install it with macports). This is obviously easier to do with the iPhone simulator than the actual device. This has been a huge help to me in debugging a lot of weird HTTP-related issues. Also, have you tried experimentally modifying your code to read from the input stream directly, just to check that the stream itself is hooked up properly? smime.p7s
