Exploring The NetCF WebCrawler Sample III - Visual Studio 2005 Beta 2

In the first part of this series, I discussed how the WebCrawler uses an HTTP HEAD request to determine if the URL can be crawled (points to an HTML page). The Visual Studio.NET 2003 version of the WebCrawler used a very simple check of the Content-Type
