Identify the previous page. 1

Suppose page1 and page2 each have a button that loads page3. Is there a way for page3 to determine which of the 2 pages called it so we can set some variables based on which of the pages loaded the 3rd?

Thanks

	X = 1
Else
	X = 4
End If

As some browsers don't send the HTTP_REFERER you may not get that server variable populated. There are also other ways to get to the 3rd form other than clicking a link. Annoying, but a fact of life.

So, if you want to be 99% sure, then I suggest that you include a querystring parameter passed from each page.

e.g. Form1.asp --> Form2.asp?frompage=1

Additionally if you have a requirement to ensure that only these pages can click through to this page, then use session variables to hold the last requested page so you can check to see if that was set (or other actions met of cours) before allowing page 3 to execute.

damber -

That's exactly what I've been doing. I was just wondering if there was a more generic way.

Thanks

cheers cory glad to have remembered my password !

crabgrass, there are a couple of different ways, but this is probably the simplest and most effective for your requirements. Unfortunately http is fundamentally a stateless protocol so either the framework or app has to build that state into the solution..
