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 - it's simply a comment then.

List of [a-e]*.shtml files in this directory: <!--#exec cmd="ls -l [a-e]*.shtml" --> Note that SSI exec is disabled for users on this site, so this directive will produce an error. The directive is enabled for the rest of this site (see linuxsig/test.shtml) - just not for users' personal pages. Attempting to do so will result in an error, as seen below.

Use another time format for file modified date. <!--#config timefmt="%l:%M:%S %P, %a, %b. %d, %Y" -->
This file was last modified <!--#echo var="LAST_MODIFIED" -->.
This file was last modified 6:23:31 pm, Sun, Oct. 07, 2007.

An alternate way is <!--#flastmod file="test.shtml" -->
6:23:31 pm, Sun, Oct. 07, 2007

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

This file size is <!--#fsize file="test.shtml" -->
This file size is 4.2K

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

Show something about your browser:
<!--#if expr="${HTTP_USER_AGENT} = /MSIE/" -->
    You are using some version of Microsoft IE Browser Be careful!
<!--#else -->
    Thank you for not using a Microsoft IE Browser
<!--#endif -->
Your browser identifies itself as <!--#echo var="HTTP_USER_AGENT" -->.

Result: Thank you for not using a Microsoft IE Browser
Your browser identifies itself as CCBot/1.0 (+http://www.commoncrawl.org/bot.html).

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.
