That's not what I'm talking about.
Disable caching on the frontend caching device when the user is logged in.
Your frontend cache is basically the same as Squid and Varnish. You have
to disable them for users because those kind of caches can never cache
user data right.
I believe Wikimedia does this by having the frontend cache check for the
user cookie.

Disabling local caching will not help my issue since
the frontend caching device is the device causing the
issue. In fact, if I disable caching (memcached and
APC) the servers will take a major hit since they will
have to re-compile the pages on every load.
Thanks for the wgShowIPinHeader I am putting that one
in right now.
Are there any other suggestions for this caching
issue?
Following the Vary headers seems like what may need to
happen, but I am looking for multiple things to try
out.
Thanks for all they help...

The first thing to do would be to disable
caching
for users. You can't
do a proper page cache when someone is logged in.
And for the IP's set $wgShowIPinHeader to false to
remove the IP from
the header.
