HTML::Mason, or just Mason for short, is a type of web application framework, distributed on CPAN, and used for websites providing dynamic content to viewers. HTML::Mason is written in the Perl programming language and is designed to work with Apache HTTP Server by using mod_perl. It also supports CGI scripting, allowing it to run on web servers with CGI enabled.
The nature and use of HTML::Mason for delivering dynamic content make it an excellent choice for online news websites and e-commerce websites with a large amount of products. For example, Amazon.com has used HTML::Mason on its website, to deliver a better e-commerce shopping experience.
