ASP.NET UrlRewriter - How to Write RegEx for Root?

Question

I have been trying to use UrlRewriter (Intelligencia.UrlRewriter.dll) in a test project.

My rewrite statement is as in the following:

<rewrite url="~/Sample/(.+)" to="~/Sample.aspx?Test=$1"/>

This statement works great for a URL like:

http://localhost:4188/RewriteTest/Sample/12345

or, let's say:

http://RewriteTest.com/Sample/12345

And, I can retrieve the value "12345" in Sample.aspx file as:

Label1.Text = "Test: " + Request.QueryString["Test"];

And when I hit the root link, it successfully displays the Default.aspx:

http://localhost:4188/RewriteTest/ or http://RewriteTest.com/

What I want to accomplish is taking the "Sample" off the regex statement, so that I can directly hit http://RewriteTest.com/12345 and display Sample.aspx by retrieving "12345" value. And, when the root is hit http://RewriteTest.com/ it will simply display Default.aspx as it is now.

Is it possible? Can the regex statement be updated to something else for this purpose?

Thank you,

If your ID code is always going to be 5 digit number then you could have clamped the regex to that:

<rewrite url="^~/([\d]{5})$" to="~/Sample.aspx?Test=$1"/>

Or a variable length number:

<rewrite url="^~/([\d]+)$" to="~/Sample.aspx?Test=$1"/>
