how to redirect in aspx page in c#

I need to redirect a page to another page directly on the server. i.e. any request to this page
http://www.elib.scot.nhs.uk/SharedSpace/rehab/Pages/Index.aspx?ContainerID=200298
should go to http://www.knowledge.scot.nhs.uk/fallsandbonehealth.aspx

I can't make change in the .cs file. I am trying to add something like this in aspx file but no luck

<%

if (!String.IsNullOrEmpty(Request.QueryString["ContainerID"]))
{
var x = Request.QueryString["ContainerID"].ToString();
if (x == "200298")
Response.Redirect("http://www.knowledge.scot.nhs.uk/fallsandbonehealth.aspx");

}

%>

Because you are working a server side push, you can try:

Server.Transfer("Webform2.aspx");

Instead of Response.Redirect.

See if that helps.

sorry it does not work I have tried the following

<%@ Page language="c#" Codebehind="Index.aspx.cs" AutoEventWireup="false" Inherits="nes.SharedSpace.Pages.Index" %>

<%

if (!String.IsNullOrEmpty(Request.QueryString["ContainerID"]))
{
var x = Request.QueryString["ContainerID"].ToString();
if (x == "200298")
Server.Transfer("http://www.knowledge.scot.nhs.uk/fallsandbonehealth.aspx");

}

%>

and when I click on http://www.elib.scot.nhs.uk/SharedSpace/rehab/Pages/Index.aspx?ContainerID=200298 I get a blank page

Evan Cutler

ok...so this is inline ASP? as in ASP Classic?

And are you looking at this as part of the page load?
or as part of a change in status to a control on the page?

One more thing:
I tried to navigate to:
http://www.elib.scot.nhs.uk/SharedSpace/rehab/Pages/Index.aspx
without the ?= element, and that page itself does not load.

Is that page missing?
Thanks

If you can't make a change in the .cs file of your code-behind, why make this a server-side script?

I'm going to assume you are using Javascript for your client script. Replace your <% %> block with:

<script type="text/javascript" language="javascript">
    if ("<%=Request.QueryString["ContainerID"].ToString()%>" == "200298")
        window.navigate("http://www.knowledge.scot.nhs.uk/fallsandbonehealth.aspx");
</script>

Open in new window

Alternatively, you can use

<script type="text/javascript" language="javascript">
    if ("<%=Request.QueryString["ContainerID"].ToString()%>" == "200298")
        window.location = "http://www.knowledge.scot.nhs.uk/fallsandbonehealth.aspx";
</script>

Open in new window

My aspx page now have the following markup

<%@ Page language="c#" Codebehind="Index.aspx.cs" AutoEventWireup="false" Inherits="nes.SharedSpace.Pages.Index" %>

<script type="text/javascript" language="javascript">
if ("<%=Request.QueryString["ContainerID"].ToString()%>" == "200298")
window.navigate("http://www.knowledge.scot.nhs.uk/fallsandbonehealth.aspx");
</script>

now I am getting an error on the page. Please click on the page to see the exact error

http://www.elib.scot.nhs.uk/SharedSpace/rehab/Pages/Index.aspx?ContainerID=200298

Let's change it up a bit:

<script type="text/javascript">
var first = getUrlVars()["ContainerID"];
if (first == 200298)
{
	window.location.href = 'http://www.knowledge.scot.nhs.uk/fallsandbonehealth.aspx';
}

	


function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
        vars[key] = value;
    });
    return vars;
}


</script>

Open in new window

I have changed the script but still getting the last error.

<script type="text/javascript">
var first = getUrlVars()["ContainerID"];
if (first == 200298)
{
window.location.href = 'http://www.knowledge.scot.nhs.uk/fallsandbonehealth.aspx';
}

function getUrlVars() {
var vars = {};
var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
vars[key] = value;
});
return vars;
}

</script>

Check out the file I gave you.
I tested it, and it went to the site as requested.
