"Connection: Close" header for WinInet in C++

I want to add the "Connection: Close" header in a request to be sent to a server.  However, it doesn't seem to be sent using the WinInet functions (and the connection is kept alive).  When I try the "Connection: Keep-Alive" header, it is sent for sure.

For example, I have:

string headers;

headers = "Connection: Close\r\n"; // this header is not sent
// headers = "Connection: Keep-Alive\r\n"; // this header is sent

// hRequest defined as HINTERNET, returned from HttpOpenRequest()
HttpAddRequestHeaders(hRequest, headers.c_str(), headers.length(), HTTP_ADDREQ_FLAG_ADD | HTTP_ADDREQ_FLAG_REPLACE);

// This also won't send "Connection: Close"
// HttpSendRequest(hRequest, headers.c_str(), headers.length(), NULL, 0);


I've only tried HttpAddRequestHeaders() and HttpSendRequest().  Is there another function, flag, etc. to forcefully add the "Connection: Close" header to a request?

This is not needed.  Just DON'T send the "Keep-Alive" request.  The non-keep-alive behavior is the default.

I simply omitted the "Connection" header and assumed the "non-keep-alive behavior is the default" as you said -- it now works.  Thanks!
