title: Using a proxy for NSURLConnection
body: <p>Is there any way to get the content of a webfile (namely a .html Document) using a proxy, which is not defined in the system settings? I know that NSURLConnection is the right way to download a web file into a variable and not into a file (for which we should use NSURLDownload), but I don't find a way to use a proxy for it.
  Are there some unofficial APIs, Libraries or Classes or such I could use for what I want to do?
  I'm not that pro in Mac Programming, so I'm searching for something more or less simple.</p>
