就安全性而言，Java已经远远低于VB.NET，更无法与安全性著称的C#相比。

能产生和执行动态、交互式、高效率的站占服务器的应用程序。运用ASP可将VBscript、javascript等脚本语言嵌入到HTML中，便可快速完成网站的应用程序，无需编译，可在服务器端直接执行。容易编写。

网页从开始简单的hmtl到复杂的服务语言，走过了10多个年头，各种技术层出不穷，单个的主流技术也在不断翻新的版本，现在分析下各种语言的区别、优势、劣势、开发注意事项！

提供基于组件、事件驱动的可编程网络表单，大大简化了编程。还可以用ASP.NET建立网络服务。

代码逻辑混乱，难于管理：由于ASP是脚本语言混合html编程，所以你很难看清代码的逻辑关系，并且随着程序的复杂性增加，使得代码的管理十分困难，甚至超出一个程序员所能达到的管理能力，从而造成出错或这样那样的问题。

由于JSP/Servlet都是基于Java的，所以它们也有Java语言的最大优点——平台无关性，也就是所谓的“一次编写，随处运行（WORA–WriteOnce,RunAnywhere）”。除了这个优点，JSP/Servlet的效率以及安全性也是相当惊人的。

但是目前在CGI中使用的最为广泛的是Perl语言。所以，狭义上所指的CGI程序一般都是指Perl程序，一般CGI程序的后缀都是.pl或者.cgi。

是目前ASP在UNIX/Linux上的应用可以说几乎为0）。所以平台的局限性和ASP自身的安全性限制了ASP的广泛应用。

关于ASP.NET功能上，ASP.NET比微软以前的ASP(96年出现)有更强大的library,更好的稳定性。ASP.NET可以使用.NETFramework中所有组件(也就是说.NET能实现的，ASP.NET一样能实现)。

微软又推出ASP.NET。这不是ASP的简单升级，而是全新一代的动态网页实现系统，用于一台WEB服务器建立强大的应用程序。是微软发展的新体系结构.NET的一部分，是ASP和.NET技术的结合。
