I have windows xp. I have IIS installed locally.

When I upload it to the web server it does some authentication.

When I test it locally, I do not want it to do the authentication (since it is local). So what I need to do is make the code check whether it is running locally, and if so skip authentication and proceed with the rest of the app.

Please not: this is nbot a Q about authentication, its simply about detecting whether I am running locally, the authentication bit is simply one example of where it would be useful.
