Drupal 7 settings.php hacks for operating behind NetIQ Access Manager

local.settings.php

<?php

/**
 * Base URL (optional).
 *
 * If Drupal is generating incorrect URLs on your site, which could
 * be in HTML headers (links to CSS and JS files) or visible links on pages
 * (such as in menus), fill in the absolute URL to your Drupal installation.
 *
 * We have to set $base_url if we're behind a Novell Access Manager proxy.
 */
if (isset($_SERVER['HTTP_VIA']) && strpos($_SERVER['HTTP_VIA'], 'Access Gateway')){
  $http_via = explode(' ', $_SERVER['HTTP_VIA'], 3);
  $base_url = 'https://' . $http_via[1];
}

/**
 * Enable this setting to determine the correct IP address of the remote
 * client by examining information stored in the X-Forwarded-For headers.
 */
$conf['reverse_proxy'] = TRUE;

/**
 * reverse_proxy accepts an array of IP addresses.
 */
# $conf['reverse_proxy_addresses'] = array('a.b.c.d', ...);

Thanks for this. Exactly what I needed. I was trying to find a way of avoiding hard-coding the base url behind access manager.
