base-url

In ASP.NET I'd like to create a link which points to a specific Uri and send this link in an email to a user, for instance something like http://www.BlaBla.com/CustomerPortal/Order/9876. I can create the second part of the Uri /CustomerPortal/Order/9876 dynamically in code-behind. My question is: How can I create the base Uri http://www.BlaBla.com without hardcoding it in my application? Basically I want to have something like:

http://localhost:1234/CustomerPortal/Order/9876 (on my development machine)
http://testserver/CustomerPortal/Order/9876 (on an internal test server)
http://www.BlaBla.com/CustomerPortal/Order/9876 (on the production server)

So is there a way to ask the server where the application is running: "Please tell me the base Uri of the application" ? Or any other way?

Thank you in advance!
