I need code for conditioned-redirection please

[Bishoy George]

Hi,

I want an asp.net code for redirection:

I have multiple domains pointing to one page , let's call it page0.aspx

I want to put a code in page0.aspx so

when domain1 opens page0.aspx it redirects it to page1.aspx
when domain2 opens page0.aspx it redirects it to page2.aspx
.... etc

Is there a code for that?

Thank you.

Hi,

Use the UrlReferrer property of the HttpRequest class. Say something
like this:

switch case(Request.UrlReferrer.ToString())
{
case "http://www.domain1.com/SomePage.aspx":
Response.Redirect("page1.aspx");
break;

case "http://www.domain2.com/SomePage.aspx":
Response.Redirect("page2.aspx");
break;
}

This code has some loop holes as in
"http://www.domain2.com/SomePage.aspx" might not be the exact string
returned by the UrlReferrer property, and you might have to use some
string handling like IndexOf() etc., but you get the basic idea, I
suppose.
Hope that helps.
Regards,
Sathyaish

You either have a firewall or some spyware detection software that is
stripping off the UrlReferrer from the Request buffer. This is a
commonly noted problem.

Look here for one possible workaround.
