ASP是Active Server Pages的简称，它是一种在微软公司的WEB服务器IIS（Internet Infomation Server）上开发交互网页的新技术。是一种服务器端的scr ipt环境。 使用asp可以建立动态,交互式高性能的Web服务器应用,我们知道,目前有很多版本的浏览器可供使用。传统上，我们在开发Web应用时，要嵌入一些scr ipt语言如VB，JAVA到html中，使这些scr ipt运行在client端，也就是浏览器，但并不是每个浏览器都支持所有的scr ipt语言，比如Netscape就不支持client端的VBscr ipt，这对我们的应用带来很大的不便。使用asp时，应用程序是在server端运行而不是在client端。当用户访问一个asp时，首先Web Server调用asp文件，并读取asp文件的全部内容后并开始执行所有的scr ipt命令，生成html页,再把这些html页传到用户端的浏览器上,并完成操作。这样，我们就不用担心用户所使用的浏览器的类型了，Web Server端已经处理了一切。微软公司最初在IIS3.0版上使用它以取代CGI。随着Windows NT在WWW上的使用日益增多，ASP已经成为了开发动态网站、构筑Internet和Intranet应用的最佳选择.-ASP is the Active Server Pages abbreviation, it is one kind (Internet Infomation Server) on develops the interactive homepage in Microsoft Corporation s WEB server IIS the new technology.

When uses asp, the application procedure is in the server end movement, but is not in the client end. When the user visits asp, first Web Server transfers the asp document, after and reads the asp document the complete content,
