SSI (Server Side Includes) 

SuperNova does support SSI. The simplest example of server-parsed HTML is to have a file "foo.shtml" containing this text:

Line one
<!--#exec cgi="mycgi.cgi" --><P>
Line three

And then have a file "mycgi.cgi" that contains, on Unix:

#!/usr/bin/perl

print "Content-type: text/htmlnn";
print "Line Two";
 

And when you access "foo.shtml", it will output:

Line one
Line two
Line three
 

If your include directive is <!--#exec cgi="..." -->, then the cgi program you run must output a standard CGI header (Content-type: text/html)
 

Any file named foo.shtml will be parsed automatically by Apache on our servers.
Do not put any spaces before the '#' character in your include directives; if you have "<!-- #exec" instead of "<!--#exec", the line will be ignored.

Server-side includes in "custom trailers" will not work, since custom trailers are appended to the output of your web pages after all other processing has been done on them. Any server-side includes that you put into your custom trailers will be sent directly to the browser without being parsed.

By default, we don't set up our servers to recognize server-side includes (SSIs)in regular .html pages because there is a loss in performance when every single .html page is parsed.

SSI That is Not Allowed

EXEC CMD

.shtml page shows up as code

If this happens, SSIs haven't been enabled for the domain. You need to contact SuperNova at support@super-nova.net and we will enable it for you.

Parsing .html as well as .shtml

By default, we don't set up our servers to recognize server-side includes (SSIs) in regular .html pages because there is a loss in performance when every single .html page is parsed. 

IF YOU ARE NOT USING FRONTPAGE, you can set this up as a Mime Type in an .htaccess file.

Open the .htaccess file in the domain-www directory and add this line, or create a file named .htaccess and insert just this line:

AddType text/x-server-parsed-html .html

If they are using FrontPage, you are out of luck. Using an .htaccess file will mess up FrontPage.

SSI test program

Simple SSI program to test if SSIs are set up to work on your domain:

#<HTML>
#<Head><Title>I was modified</Title></Head>
#<Body>
#<H1>I was modified</H1>
#<P>I was last modified on 
#<!--#echo var="LAST_MODIFIED" -->
#</P>
#</Body>
#</HMTL>

Save this as something like test.shtml in yourdomain.com-www and call it from a browser. If LAST_MODIFIED is replaced by the file creation date and time, SSIs work.
