为什么国外网站服务器很少支持JSP程序

There are several reasons for this.

First, JSP is a technology that is relatively new and not as widely adopted as other technologies such as PHP and ASP.NET.

Second, JSP is a technology that is specific to the Java platform. While the Java platform is widely used, it is not as widely used as other platforms such as Windows and Linux.

Third, JSP is a technology that is not well supported by web servers. For example, the Apache web server does not support JSP.

Fourth, JSP is a technology that is not well supported by web browsers. For example, Internet Explorer does not support JSP.

Finally, JSP is a technology that is not well suited for use on the World Wide Web. JSP is designed for use in Java EE applications, which are typically deployed on servers that are not accessible to the general public.
