Heres a snip of whats in my header-inc.php i am using
VB ON IIS 6.0:
// vBulletin Integration
// Instead of using the static header/footer file specified in the Admin options
// panel, you can use your existing default vBulletin header/footer. Just change
// $vbpath and $pppath below to the proper full paths and remove the "//" slashes
// from the beginning of the 27 lines of code below. If reviewpost has an odd
// background color or squished width, you will need to edit vbulletin's default
// "header" style input box / template and change "{pagebgcolor}" and "{tablewidth}"
// (near the bottom) to your preferred background color and table width, respectively.
$vbpath ="/forums"; // changeme
$pppath ="/reviewpost"; // changeme
chdir($vbpath);
require("./global.php");
eval('$navbar = "' . fetch_template('navbar') . '";');
$vbheader = "$stylevar[htmldoctype]
<html dir=\"$stylevar[textdirection]\" lang=\"$stylevar[languagecode]\">
<head>
$headinclude";
$vbheader .= "</head>
<body>
$header
$navbar
<div align=\"center\">";
eval('$vbfooter = "' . fetch_template('footer') . '";');
$vbfooter = process_replacement_vars($vbfooter);
$vbfooter = "</div>$vbfooter";
chdir($pppath . "/");
$HTTP_POST_FILES = $_FILES;
$HTTP_POST_VARS = $_POST;
?>
