Programmatic HTTP Post returns Empty Form fields on ASPX Server Side

[ERobishaw]

Using Winform app writing a HTTP Post using the following... on the
server side, I get no form fields. Request.Form.Al lKeys.Length = 0.

If I put the field/value paris in the URL I can use
Request["FieldName"] to retrieve the values,
but POST doesn't work.

There is NO Proxy... the only thing I can think is that ASP.NET is
somehow filtering out the page because I'm obviously not posting the
viewstate??? Seems like there was some setting for this, but I can't
recall what it is.
HttpWebRequest request = (HttpWebRequest )
HttpWebRequest. Create("http://localhost/test.aspx");
WebResponse response;

string commentField = "ABCD=123";

ASCIIEncoding encoding = new ASCIIEncoding() ;
byte[] data = encoding.GetByt es(commentField );
request.Method = "POST";
request.Content Type = "applicatio n/x-www-form-urlencoded";
request.Content Length = data.Length;
Stream stream = request.GetRequ estStream();
stream.Write(da ta, 0, data.Length);
stream.Close();
response = request.GetResp onse();
//SERVER SIDE, test.aspx page
Page_Load()
{
//BREAK POINT SET HERE>>>>
//Request.Form.Al lKeys returns nothing (0 length)
}

Viewstate won't impact this code. The request object is a lower level
object provided by the HttpContext that is present in any handler be that an
ASPX or ASHX etc.

I can't explain why AllKeys has a length of 0, your calling code looks good.
Have you tried the System.Net.WebC lient object instead. It handles a lot of
this stuff for you:-

NameValueCollec tion fields = new NameValueCollec tion();
WebClient client = new WebClient();
fields.Add("ABC D", "123");
String response = client.UploadVa lues("http://localhost/test.aspx", fields);
