Mastering Apache Velocity (REPOST)

n the beginning, a Web page was a static entity that provided the same infor mation to all visitors. Developers soon wanted the ability to provide unique data for their users. A large assortment of technologies came along to address this desire--technologies like PHP, ASP, and JSP. While these languages
do solve the problem, they all lead to a much bigger issue. Adding personalization to a Web site used to entail using one of those languages and embedding it directly into the HTML tags for the site presentation. Although this intermixing of code worked, it resulted in maintainability issues. If developers wanted to alter the look and feel of a site, they had to reapply all of the personalization code to the new HTML templates, or designers had to be given access to the code to make changes directly.
