I couldn't find any hook that is called after the options are pulled out or before exec_headers is called. So you can either put

PHP Code:

$vbulletin->options['nocacheheaders'] = true; 


Or you can modify the exec_headers function to do it per page.

Great ! I just tested this in IE, FF, Safari and Opera on Windows and FF and Opera on Ubuntu and it works ! You don't need to modify any function, all you need to do is to set this:

PHP Code:

$vbulletin->options['nocacheheaders'] = true; 


before calling global.php. This is exactly what I was looking for !

Originally, I was thinking to visualize the headers that I got from the server (there is a hack for FF that allows you to do that), but I don't think that I need to install that hack any more. Since this is working in all major browsers, that means that the correct headers are sent !

It is wrong what I did above !!!

Before calling global.php, the array "$vbulletin->options" is not defined !

I don't know why it worked on a given page. Anyway, what I decided to do in the end is this:

PHP Code:

if ($vbulletin->options['nocacheheaders'] == 0)
{
    // send the no-cache headers !
    header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
    header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
} 


In other words, if the nocache headers were not already sent, then send them. I hope I didn't do any stupid mistakes this time ....
