SSL compatibility on load balanced servers

Magento doesn’t handle SSL certificates on load balanced servers very well.

Fix it with this. 

.htaccess

... SetEnvIf X-Forwarded-Proto "^https$" HTTPS=on

And stick this in index.php, before the Mage::run line

foreach (array(    'SERVER_PORT' => 443,    'HTTP_X_FORWARDED_PROTO' => 'https',    'HTTP_CF_VISITOR' => '{"scheme":"https"}' ) as $key => $value) {    if (isset($_SERVER[$key]) && $_SERVER[$key] == $value) {        $_SERVER['HTTPS'] = 'on';        $_SERVER['SERVER_PORT'] = 443;        break;    } }

You may only need one or the other depending on your setup, but both also works fine.

Dynamic robots.txt (multiple domains)

.htaccess

... RewriteRule  ^robots\.txt$ /robots.php [NC,L] ...

robots.php

<?php $file = 'robots.txt'; if (file_exists(dirname(__FILE__).'/robots/'.$_SERVER['HTTP_HOST'].'.txt')) {     $file = dirname(__FILE__).'/robots/'.$_SERVER['HTTP_HOST'].'.txt'; }

$robotsTxt = @file_get_contents($file); header("Content-Type:text/plain"); echo $robotsTxt;

Default file is robots.txt. Additional domain robot.txt files are in a folder called “robots” named after the requested domain. I.E. robots/www.domain2.co.uk.txt

301 redirect index.php URLs to non index.php

.htaccess

RewriteEngine on ... RewriteCond %{THE_REQUEST} /index\.php [NC] RewriteRule ^(.*?)index\.php/?$ /$1 [L,R=301,NC,NE] ...

Note: You will have to comment this out when using Magento Connect as it interferes.
