How to 301 redirect old URLs from a JSP site to an ASP.NET site?

Hello:
I am migrating a website that was once hosted on an Apache/Tomcat environment running JSP. We now have it converted to C# and moved to an ASP.NET platform.

So as not to affect our SEO rankings, how do I handle the old URLs?  I can't seem to get this to work in global.asax.

For example, on the old site we have the following URL:

http://www.mysite.com/programs/program-schedule.jsp

It now points to:

http://www.mysite.com/schedules/program-schedule.aspx

I've tried looking for the request URL in the global.asax file using either Application_Start() or Application_BeginRequest(), but what happens is the 404 catches first and it just takes it to the 404 page.  I can't seem to capture what the user has entered and then perform a 301 redirect on that page.

Any ideas?  Attached is the code that DOESN'T work.
void Application_BeginRequest(Object sender, EventArgs e)
    {
        string strAbsolutePath = System.Web.HttpContext.Current.Request.Url.AbsolutePath.ToString();
        string[] aAbsolutePath = strAbsolutePath.Split('/');
 
        if (aAbsolutePath[1] != null)
        {
            switch (aAbsolutePath[1])
            {
                case "programs":
                    RedirectExternal("http://www.mysite.com/schedules/program-schedule.aspx");
                    break;
 
 
                default:
                    //do nothing
                    break;
            }
 
        }
}
 
protected void RedirectExternal(string nURL)
    {
        // Perform a 301 Redirect.
        Response.Clear();
        Response.Status = "301 Moved Permanently";
        Response.AddHeader("Location", nURL);
        Response.End();
    }

Mohan:

Thanks for the links.  Unfortunately, these pages reflect rudimentary tutorials and explanations about what a 301 redirect is and 301 best practices, both of which I'm already familiar.  They do not address my specific issue.

Thanks again.

Since no answer is forthcoming, I've researched and found an ISAPI plugin that looks like it will achieve what I want.
