Asp.net routing to mask out physical folder in path

Question

To better organise my ASP.Net project I placed all my .aspx files in a folder called WebPages.

I would like to find a way to mask out the 'WebPages' folder out from all my URLs. So for example, I do not want to use the following URLs:

http://localhost:7896/WebPages/index.aspx
http://localhost:7896/WebPages/Admin/security.aspx

But instead, would like all my URLs to be as follows ('WebPages' is a physical folder that I use for structuring my work, but should not be visible to the outside world):

http://localhost:7896/index.aspx
http://localhost:7896/admin/security.aspx

I was able to come up with a solution of my own by specifiying routing entries 'for every page' that I have in my project (and it works), but that is simply not maintainable going forward and I need another method.

public class Global : HttpApplication
{
    protected void Application_Start(object sender, EventArgs e)
    {
        RegisterRoutes(RouteTable.Routes);
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.MapPageRoute("", "index.aspx", "~/WebPages/index.aspx");
        routes.MapPageRoute("", "admin/security.aspx", "~/WebPages/Admin/security.aspx");
    }
}

Perhaps what I am after is a class that catches all requests, and simply appends my 'WebPages' physical directory?

Answer 1

I finally went ahead with the following solution which works well for my situation:

In my Global.asax file, I have the following code:

public class Global : HttpApplication
{
    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        if (Request.Path.EndsWith(".aspx"))
        {
            FixUrlsForPages(Context, Request.RawUrl);
        }
    }

    private void FixUrlsForPages(HttpContext context, string url)
    {
        context.RewritePath("/WebPages" + url);
    }
}

It is pretty much doing what Tudor has suggested but in code instead of the web.config (which I couldn't get working).
