Hello,

I am posting some credit card info to the payment
server via a similar code. My code is written in VB.NET
but uses the same approach. At the end however I do a
response.write(streamReader.ReadToEnd());

----------------------------------
string stringPost = Request.Form.ToString(); // remember a
post is essentially a string delimited in a special way
....

// Here typically you should accept the form elements
(e.g., Request.Form.Get("txn_id")) and store them in local
variables.
....
HttpWebRequest httpWebRequest = (HttpWebRequest)
WebRequest.Create("https://www.paypal.com/cgi-bin/webscr");
httpWebRequest.Method = "POST";
httpWebRequest.ContentLength = stringPost.Length + 21; //
length plus 21 because &cmd=_notify-validate is 21 chars
long
httpWebRequest.ContentType = "application/x-www-form-
urlencoded";
StreamWriter streamWriter = null;
streamWriter = new StreamWriter
(httpWebRequest.GetRequestStream());
stringPost = stringPost + "&cmd=_notify-validate";
streamWriter.Write(stringPost);
streamWriter.Close();
HttpWebResponse httpWebResponse = (HttpWebResponse)
httpWebRequest.GetResponse();
using (StreamReader streamReader = new StreamReader
(httpWebResponse.GetResponseStream()))
{
stringResult = streamReader.ReadToEnd();
streamReader.Close();
}
----------------------------------

Now my question is the following. I store some information
in the session which I need after the above has executed.
Unfortunaly the session variables do not exist. But when I
close this window and go to my basket then I can see all
information which are stored in the session. So the
session variables are not lost, but they are not
accessible in the result of the httpWebResponse. Is there
a way get my session variables work there too?

Please help me out with any suggestions. This is really
URGENT for me.

Thanks

I don't see you calling any session variables in this code...

A session variable usually looks like this:
Session("SiteBgcolor") = "Blue"

Or, if you are trying call one it's just:
Color = Session("SiteBGcolor")

This code looks like the backend code for paypal's ipn conversation. Paypal
posts a transaction to the page and your code sends a response back with
what they posted to you and adds some validate text and then they send a
command response back. Not sure were the session id would come into play.
