       <b><font size=+2>SSI tags</font></b>

	<p>SSI, Server Side Includes, are similar to RXML tags and have the
advantage of being a standard supported by many web servers. It is
thus possible to write pages using SSI that are portable to other web
servers.

<p>The downside is that SSI is in no way as flexible or powerful as
RXML. The tags are placed within HTML comments, which makes it
impossible to combine different SSI tags. However, it is possible to
combine SSI tags with regular RXML tags.

<p>Challenger does not presently implement all the SSI functionality
that Apache supports.

<p>The SSI tags are:

<dl>
<p>

<dt><b><a href=config.html>&lt;!--#config--&gt;</a></b><dd>

used to configure how things
should be printed.

<p>

<dt><b><a href=echo.html>&lt;--#echo--&gt;</a></b><dd>

Prints a variable from the server
or request.

<p>

<dt><b><a href=exec.html>&lt;--#exec--&gt;</a></b><dd>

Executes a CGI script or shell
command.

<p>

<dt><b><a href=flastmod.html>&lt;--#flastmod--&gt;</a></b><dd>

Prints the last
modification date of the specified file.

<p>

<dt><b><a href=fsize.html>&lt;--#fsize--&gt;</a></b><dd>

Prints the size of the
specified file.

<p>

<dt><b><a href=include.html>&lt;--#include--&gt;</a></b><dd>

Insert a text from another
file into the page.
