Some SSI examples

A common mistake users make when first attempting to use SSI is to include a space between the <!-- and the #, perhaps because the construct resembles an HTML comment. It won't work with a space before the command.

List of [a-e]*.shtml & test files in this directory: <!--#exec cmd="ls -l [a-e]*.shtml test*" -->

The name of this file is <!--#echo var="DOCUMENT_NAME" -->
The name of this file is test.shtml

The DOCUMENT_URI of this file is <!--#echo var="DOCUMENT_URI" -->
The DOCUMENT_URI of this file is /linuxsig/test.shtml

This file size is <!--#fsize file="test.shtml" -->
This file size is 4.4K

Several variables are made available to parsed documents. In addition to the CGI variable set, the following variables are made available:

• DOCUMENT_NAME: The current filename.
• DOCUMENT_URI: The virtual path to this document (eg. /docs/foo.shtml).
• QUERY_STRING_UNESCAPED: The unescaped version of any search query the client sent, with all shell-special characters escaped with \.
• DATE_LOCAL: The current date, local time zone. Subject to the timefmt parameter to the config command.
• DATE_GMT: Same as DATE_LOCAL but in Greenwich mean time.
• LAST_MODIFIED: The last modification date of the current document. Subject to timefmt like the others.
