ASP.NET is the successor of the highly successful classic ASP. ASP.NET is a powerful server-side technology utilizing the Microsoft .NET framework. ASP.NET pages have ".aspx" extension and are executed on the server. ASP.NET hosting is practically offered by all Windows hosting companies. Different hosting companies offer different ASP.NET hosting... http://www.aspdev.org/articles/asp.net-screen-scraping/ ASP.NET and the .NET framework make it unbelievably easy to retrieve web content (that s it, whole web pages) from remote servers. You might have various reasons to retrieve remote web content, for example you might want to get the latest news headlines from popular news sites and link to them from your website. To accomplish screen scraping in classic ASP, we had to resort to COM objects like AspHttp, ASPTear and Microsoft.XMLHTTP. The good news is that the .NET framework has built-in... http://www.eggheadcafe.com/articles/20040916.asp ASP.NET SQLCacheDependency with SQLite 3.0 and Triggers By Peter A.

But, this extra power also brings new dangers. In ASP Classic, the damage caused by malicious code running on the server was somehow limited by the built-in limitations of the ASP Classic object model. In ASP.NET, due to the number of classes exposed by the .NET framework, malicious code has the potential to be much more damaging and dangerous.

With classic ASP, developers were forced to use third-party components like ASPImage and ASPPicture for dynamic image manipulation. Fortunately, with ASP.NET, those days are over. Various image manipulation capabilities are now built directly into the .NET framework classes. The .NET Framework offers several classes for image generation and manipulation.
