// DTS Issue: 609383:
// The Set-Cookie headers are being merged into one.
// There are two issues here.
// 1. When Set-Cookie headers are set through SetCookie method on the ListenerResponse,
// there is code in the SetCookie method and the methods it calls to flatten the Set-Cookie
// values. This blindly concatenates the cookies with a comma delimiter. There could be
// a cookie value that contains comma, but we don't escape it with %XX value
//
// As an alternative users can add the Set-Cookie header through the AddHeader method
// like ListenerResponse.Headers.Add("name", "value")
// That way they can add multiple headers - AND They can format the value like they want it.
//
// 2. Now that the header collection contains multiple Set-Cookie name, value pairs
// you would think the problem would go away. However here is an interesting thing.
// For NameValueCollection, when you add
// "Set-Cookie", "value1"
// "Set-Cookie", "value2"
// The NameValueCollection.Count == 1. Because there is only one key
// NameValueCollection.Get("Set-Cookie") would conviniently take these two valuess
// concatenate them with a comma like
// value1,value2.
// In order to get individual values, you need to use
// string[] values = NameValueCollection.GetValues("Set-Cookie");
//
// -------------------------------------------------------------
// So here is the proposed fix here.
// We must first to loop through all the NameValueCollection keys
// and if the name is a unknown header, we must compute the number of
// values it has. Then, we should allocate that many unknown header array
// elements.
//
// Note that a part of the fix here is to treat Set-Cookie as an unknown header

HTTP_SEND_RESPONSE_FLAG_DISCONNECT:
specifies that the network connection should be disconnected immediately after
sending the response, overriding the HTTP protocol's persistent connection features.
HTTP_SEND_RESPONSE_FLAG_MORE_DATA:
specifies that additional entity body data will be sent by the caller. Thus,
the last call HttpSendResponseEntityBody for a RequestId, will have this flag reset.
HTTP_SEND_RESPONSE_RAW_HEADER:
specifies that a caller of HttpSendResponseEntityBody() is intentionally omitting
a call to HttpSendHttpResponse() in order to bypass normal header processing. The
actual HTTP header will be generated by the application and sent as entity body.
This flag should be passed on the first call to HttpSendResponseEntityBody, and
not after. Thus, flag is not applicable to HttpSendHttpResponse.
