ReWritePath / Application_BeginRequest Question

Following code in global.asax.cs:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpContext context = HttpContext.Current;
context.RewritePath("/root/test.aspx");
}

this only works if the url has an aspx extension.  Is there any other way to accomplish url rewriting with a different extension (or none at all)?

You need to convince your web server (presumably IIS) to send all requests to the ASP.NET engine. How you do this, depends on what version of IIS you're using.

Open IIS Admin, drill into your virtual directory, and get properties. Configure the application. Delete all the default ISAPI mappings. For IIS 5.x (2000/XP), you'll add a mapping for .* to aspnet_isapi.dll (in \Windows\Microsoft.NET\Framework\v1.x.xxxx); for IIS 6, there's a special section for "default mappings", which you'll set as aspnet_isapi.dll. Uncheck the option that reads something like "Ensure file exists" (which tells the web server not to look for some file on disk, but just dispatch any URLs at all to you).

Being more specific would take a LONG time to explain. Hopefully you can muddle your way through. :)

Brad: Thank you.  I had been poking around in the mapping already and your instructions were perfectly clear.

One other option - if you're using IIS6 - is to write a wildcard ISAPI application mapping. The SDK samples provide the URL rewriting functionality you're looking for.

Greg: that's exactly what I described.
