12.1 Server Side Includes (SSI)
„
Server-side includes
“ functionality (SSI) is available in order to generate dynamic web pages,
which for example can portray process data.
The web server only scans the index.html file and files with the extensions "shtml" or "sml" for
SSI directives. In all other HTML files the SSI directives are ignored.
If a client is asking for a web page with SSI directives the web server replaces the directives with
the web server‘s instructions with the appropriate values and sends the generated page.
SSI directives are listed within HTML comments and have the following syntax:
<!--#exec=“command“-->
