Proxy Authentication.

[Nihilanthyc]

I'm currently trying to create software to monitor all computers of the company where I work. As they use proxies, I can't use the library to test their network speed. Can you provide some help about that?

System.AggregateException
  HResult=0x80131500
  Message=One or more errors occurred. (Response status code does not indicate success: 407 (Proxy Authentication Required).)
