Bug 184314 (rhn-freakyfriday)

Users are still getting switched around.  The problem was with our cookies and
images:

1) user requests

http://rhn.redhat.com/rhn/help/reference/rhn405/en/stylesheet-images/tip.png

we send back the image and the headers:

Set-Cookie:
rh_auth_token=4483454:1141758581x7ab3843112841343b95825029e2e214b;
Domain=.redhat.com; Expires=Tue, 07-Mar-2006 20:09:41 GMT; Path=/
Set-Cookie:
pxt-session-cookie=2507456287x371ef042b7ba65eb81782069dfe79d28;
Domain=rhn.webqa.redhat.com; Expires=Tue, 07-Mar-2006 20:09:41 GMT;
Path=/; Secure

2) our apache proxy that sits in front of the java/tomcat box sez: "Hey, this is
an image, lets cache it!".  So it caches the image, but also caches the headers
from step 1.

3) another user requests:

http://rhn.redhat.com/rhn/help/reference/rhn405/en/stylesheet-images/tip.png

they were logged in as themselves, but suddenly they are logged in as user from
step 1.

This is because the proxy layer said: "hey, I have this in my cache, lets give
it back to the user" but not only did they get the image, they also got the
cookies from user1.

Switcharoo.

The reason we didn't see this until 405 was the docs weren't being served from
tomcat until 405 was released and all the other images that RHN uses are served
from apache and don't have this issue.
