LinuxQuestions.org - How to run a server-side Javascript in Apache

I am running an Apache web server under Linux.
The Java script below suppose to write a file
named servertype.conf to a web server under
the directory /var/apache/.

The Java script responded properly but it did not create a file.
This Java script is embedded within a Python script, and the
Pyhton script does run.
There is an error. Error 'File is undefined'

The code var mysummary = new File("/var/apache/servertype.conf")
is a server-side script.
How do I get this server-side script to work in Apache ?
This code is also shown on line number 10 below.

===========================

Alternatively, I could use a Server Side Include (SSI) feature to
write to a file in a web server with the statement as showned
on line number 9 below.

The code AddHandler server-parsed .conf
would then be added to the file /etc/httpd/conf/httpd.conf

So far I could not get either of the two methods to work.
I am running Apache version 1.3.26
===========================

Code:

1) <SCRIPT LANGUAGE="Javascript">

2) <!--



//Javascript added by Linh on 7-13-2004 for switching between

//master iserver and secondary iserver



3) function select_button (form)

4)  {

5)  if (form.defms[1].checked)

6)    if (confirm ("You are changing from a master iserver 

                            to a secondary iserver. Is this what you want ? 

                            To complete this process, you must 

                            1) Enter Iserver IP address. 

                            2) Enter the Iserver Registration Password. 

                            3) and finally click the button 

                                'Apply Changes to System'") )

7)      {

8)        alert ("Clicked Yes");



9)        <!--#exec echo "ServerType=Secondary" > /var/apache/servertype.conf -->



10)    var mysummary = new File("/var/apache/servertype.conf");

        mysummary.open("w");

        mysummary.write('ServerType=Secondary');

        mysummary.flush();

        mysummary.close();



      }

    else

      {

        form.defms[1].checked = false

        form.defms[0].checked = true

        alert ("Clicked No");

      }

 }
