Httpwebresponse .cookies returning inconsistant values.

[Ravi]

Hi ,

i am trying to pass the same session Id to all the webrequest, but
sometimes the response.cookie s returns zero and sometimes one. is this to do
something with cookies expire. In this sample code the line

Console.WriteLi ne("cookies1 count : " + firstResponse.C ount.ToString() ); and
Console.WriteLi ne("second Cookie : " +
secondResponse. Cookies.Count.T oString());

print different values (0 or 1) each time the sample code is complied and
runned. Any help and suggestion will be a great help forme.
The Sample code is as follows.
HttpWebRequest req =
(HttpWebRequest )WebRequest.Cre ate(@"http://localhost/Test/WebForm1.aspx?u sr=test&pwd=tes t");
string postData = @"usr=test&pwd= test";
ASCIIEncoding encoding=new ASCIIEncoding() ;
byte[] byte1=encoding. GetBytes(postDa ta);

req.ContentType = @"applicatio n/x-www-form-urlencoded";

req.Method="POS T";
req.ContentLeng th = postData.Length ;
req.KeepAlive=t rue;
Stream reqStream = req.GetRequestS tream();
reqStream.Write (byte1,0,byte1. Length);
reqStream.Close ();

req.CookieConta iner = new CookieContainer ();
HttpWebResponse firstResponse = (HttpWebRespons e)req.GetRespon se();
Console.WriteLi ne("first response : " + firstResponse.S tatusCode.ToStr ing());
Console.WriteLi ne("cookies1 count : " + firstResponse.C ount.ToString() );

HttpWebRequest secondRequest = (HttpWebRequest )
WebRequest.Crea te(@"http://localhost/Test/WebForm2.aspx") ;

secondRequest.C ontentType = @"applicatio n/x-www-form-urlencoded";
secondRequest.M ethod="POST";
secondRequest.C ontentLength = postData.Length ;
secondRequest.K eepAlive=true;
reqStream = secondRequest.G etRequestStream ();
reqStream.Write (byte1,0,byte1. Length);
reqStream.Close ();
secondRequest.K eepAlive=true;
secondRequest.C ookieContainer = new CookieContainer ();
CookieCollectio n cookies1 = firstResponse.C ookies;

secondRequest.C ookieContainer. Add(cookies1);

HttpWebResponse secondResponse = (HttpWebRespons e)secondRequest .GetResponse();

Console.WriteLi ne("second Response : " +
secondResponse. StatusCode.ToSt ring());

Console.WriteLi ne("second Cookie : " +
secondResponse. Cookies.Count.T oString());

You only need one CookieContainer instance. CookieContainer keeps track
of all cookies automatically, so there's no reason to copy cookies from
the response to the container.
