By default, dynamic output is not re-parsed for SSI inclusion (or any other 'after-effects'). However, two ways exist to use SSI (or it's near equivalent). Either use the module CGI::SSI which allows you to call SSI from the perl script, or use a templating solution such as HTML::Template, Template Toolkit 2 or HTML::Mason that can be used to include fixed parts of other files before sending the page off.
