Remarks
The following sample code shows a method to get and set the Proxy-Authenticate header on an HttpResponseMessage object using the ProxyAuthenticate property on the HttpResponseHeaderCollection object.
// Proxy-Authenticate: Basic
// HttpChallengeHeaderValueCollection
// HttpChallengeHeaderValue has Scheme and Token (both strings) + Parameters
// Parameters is an IList<HttpNameValueHeaderValue>
// HttpNameValueHeaderValue has Name and Value, both strings
void DemoProxyAuthenticate(HttpResponseMessage response) {
var h = response.Headers;
h.ProxyAuthenticate.TryParseAdd("Basic");
h.ProxyAuthenticate.Add(new HttpChallengeHeaderValue("digest", "token"));
var header = h.ProxyAuthenticate;
uiLog.Text += "\nPROXY AUTHENTICATE HEADER\n";
foreach (var item in header) {
// Parameters is an IList<HttpNameValueHeaderValue> of Name/Value strings
var parameterString = "";
foreach (var parameter in item.Parameters) {
parameterString += string.Format("[{0}={1}] ", parameter.Name, parameter.Value);
}
if (parameterString == "") {
parameterString = "(no parameters)";
}
uiLog.Text += string.Format("Scheme: {0} Token: {1} Parameters: {2} ToString(): {3}\n", item.Scheme, item.Token, parameterString, item.ToString());
}
uiLog.Text += String.Format("ProxyAuthenticate: {0}\n", header.ToString());
