I would like to execute a frame redirect in C# from my managed module

  • 0

I would like to execute a frame redirect in C# from my managed module for the IIS 7.

When I call context.Response.Redirect(@"http://www.myRedirect.org");the correct page is shown but also the address is shown in the browser. And that is exactly what I do not want.

So I want something like:

private void OnBeginRequest(object sender, EventArgs e)
{
    HttpApplication app = (HttpApplication)sender;
    HttpContext context = app.Context;

    // make a frame redirect if a specified page is called
    if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html"))
    {
        // perform the frame redirect here, but how?
        // so something like
        context.Response.Redirect(@"http://www.myRedirect.org");
        // but as I said that doesn't redirect as I want it to be
    }
}

Any ideas about that?

EDIT:
I tried the example, so I have:

private void OnBeginRequest(object sender, EventArgs e)
{
    HttpApplication app = (HttpApplication)sender;
    HttpContext context = app.Context;

    // make a frame redirect if a specified page is called
    if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html"))
    {
        // perform the frame redirect here, but how?
        context.Response.Write(@"<html>");
        context.Response.Write(@"<head>");
        context.Response.Write(@"</head>");
        context.Response.Write(@"<frameset rows=""100%,*"" framespacing=""0"" frameborder=""NO"" border=""0"">");
        context.Response.Write(@"<frame src=""http://www.myRedirect.org"" scrolling=""auto"">");
        context.Response.Write(@"</frameset>");
        context.Response.Write(@"<noframes>");
        context.Response.Write(@"<body>Some text...");
        context.Response.Write(@"</body>");
        context.Response.Write(@"</noframes>");
        context.Response.Write(@"</html>");
    }
}

But that also doesn’t correctly redirect. I still have the redirect address shown in my browser. So any other idea?

EDIT:
I obviously made a mistake. The code above works and does what I want. It first didn’t work because my redirect url was doing something unexpected.

    To perform a frame redirect you need to send back the HTML code containing a frameset with a single frame, with it’s source set to http://www.myRedirect.org. As far as the server and browser is concerned no redirect has happened – it’s just received some HTML code.

    Performing a Response.Redirect will, as you’ve observed, cause the browser to make a fresh new request to the new page, showing the user the new address in the title bar. It’s typically used for when a page actually changes its address, but the owners still want it reachable from the original URL as well.
