PUT on OS X (NSURLConnection)

[Robert Sayre <mint@xxxxxxxxxxxxxxx>]

I read the following on Ecto author Adriaan Tijsseling's blog:

"10.3.7 was released yesterday. It fixes several issues with WarCraft, 
but yet again it does not fix a huge bug in the NSURLConnection 
framework: HTTP PUT lacking a body."[0]

Basically, it drops the body if the method is anything other than POST. 
However, Adriaan also posted a little demo XCode project that 
illustrated the issue with NSURLConnection.[1]

I took his demo, and modified it to use CoreFoundation HTTP 
functions[2]. Using CoreFoundation is a PITA, but it works and is 
guaranteed to be there. There are some niceties missing that you get 
from NSURLConnection (e.g. detecting system proxy settings), but they 
could be added and are mostly geared towards browser-esque apps. So, 
here's PUT in Cocoa:

The connection class is not very robust, it's just a proof of concept, 
so there would be more work to do in order to use it in something like 
Ecto. But not that much.
