Nginx Multisite redirects (incorrectly) on Chrome IE and Mobile, but works (correctly) on Firefox

Question

I'm having an issue that I can't find anybody else talking about anywhere. I have a wordpress multisite setup utilizing sub-directories. It's running on Debian Squeeze, and it's powered by nginx, php 5.4, and php5-fpm.

Currently I am using the batcache plugin and the advanced apc caching plugin from mark jaquith.

The Bad: So, the problem I'm having is that when I access the site with either IE, Chrome or by mobile, it always redirects back to the root site. The only time it doesn't is when accessing wp-admin.

The Good: The whole setup works perfect on firefox. I have ran some curl -I passes on the site to get the header info. Here are the results: http://pastebin.com/VryGXAAY

What I've Tried: I have cleared the browser cache. Tried it on a different machine. And yelled at it a lot.

Here is a copy of the config files:

sites-enabled/example.com: http://pastebin.com/69xsMuwb

globals/mu-dir.conf: http://pastebin.com/CSup1q1h

globals/mu-files.conf:

# Rules for any Multisite install
# For uploads
if ( $uri ~ "files" ) {
    rewrite ^/(?:.*/)?files/(.+) /wp-includes/ms-files.php?file=$1;
}

globals/restrictions.conf: http://pastebin.com/rhrr5Qkf

globals/common-locations.conf: http://pastebin.com/GiYBRP1y

Let me know what other info you might need. Any help would be appreciated! :)

Alright I figured it out. Thank you guys. What it came down to was a little snippet of code I put in a while back to redirect a user to the home page if not logged in.... stupid me.

I really appreciate your help in this though. By disabling everything but wordpress (all plugins, caching, everything.) it still happened. I decided to change the theme used on my root site to the same theme used on the sub-sites and it resulted in an endless redirect. boom. That's when the light turned on.

Thanks again! -Chase

And if anybody wants that code, here it is: it word pretty well! :)

<?php if (
  !in_array($GLOBALS['pagenow'], array('wp-login.php', 'wp-register.php'))
  && !is_admin()
  && !is_user_logged_in()
) {
  wp_redirect('http://www.example.com/', 301);
  exit;
}
?>
