Screen Scrape of www.yahoo.com

This demo illustrates how to perform a screen scrape using the WebClient class. Note that only a few lines of code are needed. (With classic ASP, to perform screen scrapes you needed to use a third-party component.) To view the actual HTML returned by the screen scrape, do a View/Source.
