Class 'COM' not be found on my Apache

Betty_S

When I tried to write:

$shell = new COM("WScript.Shell") or die("This thing requires WindowsScripting Host");

I get this:

Class 'COM' not found in /var/www/vhosts/rt-design.co.il/httpdocs/templates/rt-design/index.php on line 2

Basically, I want to prevent my site from being cached.
I tried .htaccess, php header and even JavaScript but nothing works!
Whats the the deal with the COM?! Shouldn't that be a basic object?!
Please help me.

What kind of headers have you tried?

How would using a COM object prevent browsers from caching your site?

Betty_S

I tried a no-cache header.
I need the COM for that:

$shell = 
new COM("WScript.Shell") 
or die("This thing requires WindowsScripting Host");
$registry_proxystring =
$shell->
RegDelete("HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\Cache\\History\\");

Right: as if any random site could edit my machine's registry. You want to do anything with my browsing history, CV, financial records, system drivers and pr0n collection as well?

You do realise that PHP runs on the server, right? That would be the server's registry you're trying to delete stuff from.

Why are you so determined to empty out IE users' caches? They're not yours to empty. And are you going to go after users of other browsers next?

Please do not misunderstand me,
I get no special pleasure from editing users machine's registry (or even there pr0n collection).
As I wrote before, I want to stop the page from being cashed.
Please assist,
Thanks.

He's being sarcastic - PHP runs on the server, not on the client's computer. The only registry you're editing is the server's (assuming the server is even running a Windows computer and has rights to edit the registry).

Oh and by the way

/var/www/vhosts/rt-design.co.il/httpdocs/templates/rt-design/index.php

is not a winders file path so you must be on a Linux box which of course won't have COM.
