The reason that the domain is in the request is...that's what's being asked for. For example these are a few stackexchange sites from http://www.stackexchangesites.com/:

• http://community.ecoanswers.com
• http://www.appqanda.com
• http://www.irosetta.com/

If you ping them, you'll see they all point to the same IP/Web Server and be served by the same app (or multiple apps in this case, but the example holds if it was one big one)...but the application doesn't know which one until a host header comes in with the request asking the server for that site. Each request may be to a different domain...so the application doesn't know it.

If however it doesn't change, you could store it as an appSetting in the web.config.

HttpRuntime.AppDomainAppVirtualPath

Or if you want the physical path:

HttpRuntime.AppDomainAppPath

Use global.asax or write a HttpModule and subscribe to start request events. You will have the request passed into your event handler.
