ASP.NET Server.Transfer & Server.Execute

ASP.NET Server.Transfer & Server.Execute

1. Server.execute  : go to other site , do processing and return.

Will show the Default2.aspx . Url not changed. We have both pages webcontrol. URL will changed after the postback and Response stream & Web control of previous page will lost.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        Session("eid") = "009383"

        Session.Timeout = 1  'make session for 1 minute

        'Server.Transfer("Default2.aspx")  'page accessed without changing url

        Server.Execute("Default2.aspx")

    End Sub

2. Server.Transfer will show the Default2.aspx page without changing url will access here the response stream of Default.aspx page.& Web Control of Default.aspx page will lost. No Roundtrip. URL will changed after the postback and Response stream ( Web controls already) of previous page will lost.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        Session("eid") = "009383"

        Session.Timeout = 1  'make session for 1 minute

        Server.Transfer("Default2.aspx") 

    End Sub

Here is the Default2.aspx Page for both methods shown above

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Response.Write("Page2")

    End Sub

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        Response.Write(Session("eid") & "v")

        '   Session.Clear()   ''clear the value part of session

       

    End Sub

3. Response.Redirect("Default.aspx") will completley nevigate to other page. Kill response stream as well as web controls of calling page.
