Thanks, Espavo. We already thought of using a web service on Server2, but for various reasons, decided to try to do this with HttpRequest/Response or HttpWebRequest/Response which we need to explore first.

Question
How to Transfer data between two aspx pages on different servers?
After reading many references (Microsoft and others) to HttpWebRequest/Response and HttpRequest/Response, and trying several different approaches, I still unable to make this work. The issue is to successfully transfer data from source.aspx on server1 to target.aspx on server2, processing it on server2 and returning the results to source.aspx on server1.
Specifically, on server1, source.aspx the client enters UserName and ProductID. It is validated in source.aspx.vb, and then is sent to target.aspx on server2. Target.aspx receives data, processes it by several methods in code behind and returns the result, e.g. ProductLicenseKey to server1, source.aspx for display to the client. There may be a 5-10s delay in processing in target.aspx.vb.
Eventually the information will be sent via https and possibly encrypted, but that is not the issue now.
I would appreciate any response (prefer VB, but C# would help) that you experts could provide.

Romasa, as you can tell from my question, I am pretty much of a beginner with the various Request/Response classes. Since I have not been able to successully transfer two strings, UserName and ProductID to target.aspx which runs a separate process and returns the ProductLicenseKey (string) I don't understand how. I.e. which class to use to send text or xml to target.aspx and which class to use to return text or xml to source.aspx?
I have used following code to check the fields of my previous page and response accordingly, but for this you have to set autopostBack event of previous page to true
And in the current page, you can use following code in page load event:
protected void Page_Load(object sender, EventArgs e)
{
if (PreviousPage != null && PreviousPage.IsCrossPagePo
{
DropDownList ddlBeacontype = new DropDownList();
ddlBeacontype = (DropDownList)PreviousPage
indexNum = ddlBeacontype.SelectedInde
}
}
In this piece of code, i have checked the selected value of DropDownList of previous page into the current page and the current page will navigate to the next page according to the values selection of DropDownList.
You can use this for any control of asp.net, it will work
Let TextBox1 and TextBox2 fetch the UserName and ProductID on Server1/MyFirstSite/Defaul
On the button 1 add the following click handler
protected void Button1_Click(object sender, EventArgs e)
{
string UserName = TextBox1.Text;
string ProductID = TextBox1.Text;
Response.Redirect("http://
}
When user clicks the button, the last line will redirect your call to server2 page that generates the license.
Now for the second part: On server2 you need the following page: licensesite/generatelicens
and code this event:
protected void Page_Load(object sender, EventArgs e)
{
System.Diagnostics.Debug.W
string UserName = Request["uname"];
string ProductID = Request["pId"];
string ProductLicenseKey = CalculateProductLicenseKey
Response.Redirect("http://
}
Finally you need to create this page on server1 (Server1/MyFirstSite/MyLic
and code this event:
protected void Page_Load(object sender, EventArgs e)
{
System.Diagnostics.Debug.W
string ProductLicenseKey = Request["plkey"];
// Do some code that uses ProductLicenseKey
}
The code is oin C# but the key idea is to use the Response.Redirect method to send parameters and
Request["parameterName"] to retrieve them
