Read Web Text File

I have a text file and I have an Classic ASP web page. I am trying to read the contents of the text file. The text file and the web page are always going to be in same folder. However, I want a generic solution that doesn't require hard coding the link to the test file. This way I can clone the code to another folder or web site without a lot of extra hassles. This should be easy but I haven't found a wya to consistently do it.
