I have previously built sites using PHP, where I automatically included header and footer html using the following lines in .htaccess on an Apache host:
php_value auto_prepend_file "/var/www/html/parts/header.htm"
php_value auto_append_file "/var/www/html/parts/footer.htm"
In these files I could put executable PHP code.
My current project is written in Perl, not in PHP.
Is there any way to automatically prepend and append executable Perl files using .htaccess?
