There are lots of program frameworks around for different programming languages to simplify the development of web applications, sometimes though there is a time once the ready-made solutions don’t cover what you want to do or don’t do what you need in an instinctive manner. A program framework is often referred to as middle-ware or back-end system. Frequent items included to make live easier in creating a web site front-end are managing of database discussion, templating for content and output files, communicating with remote servers, configuration of web site, and managing email. In this article I aim to outline how you can make this operation through an object-orientated mod_perl strategy.
The front-end ought to make use of different objects for each page/functional unit of their web site and ought to inherit from the base class, for our purposes we will call this Base.pm.
Base course, Configuration & Control flow
A worldwide configuration for your site can be used to keep common attributes into the web environment, this would include paths and URL locations of content, BIN database, pictures, etc.. You might also include avenues to email program or SMTP host used for sending email. Locations of template documents you may use for articles also needs to be specified in a configuration file. Other features such as domain name, database details like name, password and user, place of apache http auth password documents and general goal apache configuration directives. A good way to start developing a system setup is by specifying exactly what you need in a Perl module and call it Constants.pm and include it in the base class you’re using to build frame. An example might look something like
