KFactor-
If you want to pass a value to another server, but don't want the value to
be visible to the user in the url, you might try sending
the value in a cookie. In the first page:
Response.Cookies.Add(new System.Web.HttpCookie("userID", "300"));
Response.Redirect("http://somserver.net/Test.aspx");
Inside the destination page:
this.Response.Write("User ID is " + this.Request.Cookies["userID"].Value);
This scheme will pass a value from server to server, without the value
being in the querystring. Of course, it's not the least bit
_secure_, as the cookies are sent in the HTTP request, and it's not
difficult to look at the request.
Another suggestion:
Do you want the data to be secure? You could encrypt the userID on the
first machine, attach it to the querystring (or put it in a
cookie), and decrypt it on the target machine.
System.Security.Cryptography has some classes that will let you encrypt
and decrypt text (DESCryptoServiceProvider is your friend
here). If you can distribute a shared secrect key to both servers, the
encrypted userID will be pretty safe unless someone gets hold
of the secret key.
Hope this helps,
