Question in ASP.Net

Hi all,
I am new to the world of ASP.Net programming and i want to know if i am on a page isthere is anyway to know the url or the previous page to it.

ie for example if my application is 3 pages and i am on the page number 3
how i know if i came to it by page 1 or page 2.

thanks in advance.

This is something you would track behind the scenes, perhaps in a session variable.

Also, if they got directed to your site/page through a link:

VB Code:

If Not Page.Request.UrlReferrer Is Nothing Then
            Response.Write(Page.Request.UrlReferrer.AbsoluteUri)
        End If

Will give you info about the source page.
