title: How do I make an HTTP Post with HTTP Basic Authentication, using POCO?
body: <p>I'm trying to make an HTTP Post with HTTP Basic Authentication (cleartext username and password), using POCO.  I found an example of a Get and have tried to modify it, but being a rookie I think I've mangled it beyond usefulness.  Anyone know how to do this?</p>
  
  <p>Yes, I've already seen the other SO question on this: <a href="https://stackoverflow.com/questions/1499086/poco-c-net-ssl-how-to-post-https-request">POCO C++ - NET SSL - how to POST HTTPS request</a>, but I can't make sense of how it is trying to implement the username and password part.  I also don't understand the use of "x-www-form-urlencoded". Is this required for a Post? I don't have a form.  Just want to POST to the server with username and password parameters.</p>
