Per-page redirection in IIS7

daymobrew

I am tweaking the FeetFirst.ie web site. I had to redirect 3 pages to 3 different internal urls e.g.
http://www.feetfirst.ie/page.aspx?pageid=592 -> http://www.feetfirst.ie/page.aspx?subsectionid=634

The hosting company's knowledge base says that ISAPI Rewrite 3 is installed which means that it uses .htaccess and that the rules are interchangeable with Apache's mod_rewrite.

I tried the following but it did not work:

RewriteEngine on

Redirect 301 /page.aspx\?pageid=592 http://www.feetfirst.ie/page.aspx?subsectionid=634
Redirect 301 /page.aspx\?pageid=593 http://www.feetfirst.ie/page.aspx?subsectionid=619
Redirect 301 /page.aspx\?pageid=594 http://www.feetfirst.ie/page.aspx?subsectionid=62

The hosting company would not help. They would only confirm that ISAPI Rewrite was enabled on the server.

I ended up implementing it in the C# files but I am not happy with this solution (this was hacked into existing code in the page.aspx file):

<script runat="server">
    int GetParameter(string Name)
    {
        try
        {
            return int.Parse(Request.Params.Get(Name));
        }
        catch
        {
            return 0;
        }
    }
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            int SectionID = GetParameter("SectionID");
            int SubSectionID = GetParameter("SubSectionID");
            int PageID = GetParameter("PageID");

            // Redirect some pages to others, based on code from: http://www.rapidtables.com/web/tools/redirect-generator.htm
            // Redirect Mizuno 5k Winter Series left menu page to section in black menu.
            if (PageID == 592) {
              Response.Status = "301 Moved Permanently";
              Response.AddHeader("Location","http://www.feetfirst.ie/page.aspx?subsectionid=634");
              Response.End();
            }
            // Redirect Good Friday Run left menu page to section in black menu.
            if (PageID == 593) {
              Response.Status = "301 Moved Permanently";
              Response.AddHeader("Location","http://www.feetfirst.ie/page.aspx?subsectionid=619");
              Response.End();
            }
            // Redirect Killarney Women's Mini Marathon left menu page to section in black menu.
            if (PageID == 594) {
              Response.Status = "301 Moved Permanently";
              Response.AddHeader("Location","http://www.feetfirst.ie/page.aspx?subsectionid=628");
              Response.End();
            }
        }
    }
</script>

What am I doing wrong in .htaccess?
Is there a super simple test that I can add to .htaccess to confirm that ISAPI Rewrite is enabled and working?
