SSI on Debian

Server Side Includes are an old fashioned way to enable active web server content. Debian provides a module

  /etc/apache2/mods-available/include.load

but lacks a configuration file. This configuration enables SSI for SHTML files.

<IfModule mod_include.c>
  <Location />
    Options +Includes
    AddType text/html .shtml
    AddOutputFilter INCLUDES .shtml
    DirectoryIndex index.shtml

</IfModule>
