Of course you can extend <B>WWWdb</B> with your own functionality. Therefore
we have a concept called Plugins.

<BR><BR>

Plugins are subprocedures in perl, which allow you to control the
application-flow. For the communication with <B>WWWdb</B> an API does
exist.

<BR><BR>

Some Plugins allow a <i>Pre</i>, <i>My</i> and
<i>Post</i>-functionality. In detail this means:

<ul>
<li><i>Pre</i>  - This plugin is called <i>before</i>
                  the system-defined function</li>
<li><i>My</i>   - This plugin is called <i>instead of</i>
                  the system-defined function</li>
<li><i>Post</i> - This plugin is called <i>after</i>
                  the system-defined function</li>
</ul>
