title: Getting 400 Bad Request when trying to connect to website via winsock socket
body: <p>I made a socket I've slowly been adding on to for about a week now and I've come across a problem. I set up a port on my local 127.0.0.1 ip address to allow me to connect to my own computer and when I recieve the response from my computer it says "400 Bad Request. The request is badly formed.". I think it has to do with the http header information I send via the <code>send();</code> function. <code>sendbuf</code> Contains the header information to be sent. Here's my code:</p>
  
  <pre><code>#include &lt;windows.h&gt;

  #define DEFAULT_PORT 27015

      extern string input = "";
  }
  using namespace Globals;

      do {
              printf("USERNAME: \t");
              getline(cin, input);
              if ( input == "User Name" ) {
                      break;
               }
          } while(true);
  
  }
  
  void PASSWORD() {
      do {
