Hi,

The following code works fine on a Windows Server:

private string Authenticate()
{
	//Create a web request for the Google ClientLogin service
	HttpWebRequest authRequest = (HttpWebRequest)HttpWebRequest.Create("https://www.google.com/accounts/ClientLogin 
");
	authRequest.KeepAlive = false;
	authRequest.ContentType = "application/x-www-form-urlencoded";
	authRequest.Method = "POST";
	authRequest.AllowWriteStreamBuffering = false;

	//Build the POST data
	StringBuilder postBuilder = new StringBuilder();
	postBuilder.AppendFormat("accountType={0}", GOOGLE_ACCOUNT_TYPE);
	postBuilder.AppendFormat("&Email={0}", GOOGLE_USERNAME);
	postBuilder.AppendFormat("&Passwd={0}", GOOGLE_PASSWORD);
	postBuilder.AppendFormat("&service={0}", GOOGLE_SERVICE);
	postBuilder.AppendFormat("&source={0}", GOOGLE_SOURCE);

	//Convert the POST data to a byte[]
	byte[] data = ASCIIEncoding.ASCII.GetBytes(postBuilder.ToString());
	authRequest.ContentLength = data.Length;

	//Get the request stream and POST the data
	Stream requestStream = authRequest.GetRequestStream();
	requestStream.Write(data, 0, data.Length);
	requestStream.Close();

	//Get the response
	HttpWebResponse authResponse =  
(HttpWebResponse)authRequest.GetResponse();
	Stream responseStream = authResponse.GetResponseStream();
	StreamReader responseReader = new StreamReader(responseStream);
	string response = responseReader.ReadToEnd();

	responseStream.Close();
		
	if (response.Contains("Auth"))
	{
		int index = response.LastIndexOf("=") + 1;
		string auth = response.Substring(index, response.Length - index);
		return auth;
	}
	else
	{
			throw new Exception(response);
	}
}

On Linux/Mono 1.9 however, it throws an exception:
System.Net.ProtocolViolationException: Content-Length not set at  
System.Net.HttpWebRequest.CommonChecks (Boolean putpost) [0x0008d] in / 
usr/src/mono1.9-final/mono-1.9/mcs/class/System/System.Net/

I've checked the ContentLength and data.Length values, they are both  
equal.

Any ideas?


Timothy.
