Tutorial - Object inheritance

You are free to derive your request handler classes from any base
|
||
|
|
class you wish. In most real-world applications, you will probably
|
||
|
|
want to create a central base class used for all your pages, which takes
|
||
|
|
care of things like printing a common page header and footer.
