Description of problem:

I can use wget and lynx to log into RHN and retrieve
https://rhn.redhat.com/rhn/YourRhn.do, but not
https://rhn.redhat.com/network/software/download_isos.pxt

I have traced this to an inability of lynx and wget to store cookies which
expire after Tue, 19-Jan-2038 03:14:07 GMT, aka gmtime(2**31-1). 

For some reason, the pxt-session-cookie cookie is set to expire well beyond that
date. In my test just now, it was set to expire on Sun, 27-Sep-2043 17:03:58 GMT. 

While this isn't necessarily a bug with RHN, exactly, it's the first time I've
seen a cookie set to expire beyond 2038. And given that it claims to be a
session cookie, which I'd expect to have a shorter lifetime than 36 years, it
seems odd.

Version-Release number of selected component (if applicable):

Red Hat Network release 4.1.5, as reported by rhn.redhat.com.

How reproducible:

Log into https://rhn.redhat.com/ with the LiveHTTPHeaders firefox extension
turned on and examine the Set-Cookie headers sent by the server.

Steps to Reproduce:
1. Download, install and enable LiveHTTPHeaders from
http://livehttpheaders.mozdev.org/
2. Log into https://rhn.redhat.com/rhn/YourRhn.do
3. Examine the Set-Cookie headers sent by the server.
  
Actual results:

An expiration date past 2038:

Set-Cookie: pxt-session-cookie=3013414990x86e8a634f140eb23457c66bde1907af5; Doma
in=rhn.redhat.com; Expires=Sun, 27-Sep-2043 17:03:58 GMT; Path=/; Secure

Expected results:

A more reasonable expiration date, such as this one:

Set-Cookie: rh_user=uwjdlarios|Joshua|customer|; Domain=.redhat.com; Expires=Wed
, 14-Nov-2007 08:01:59 GMT; Path=/

Additional info:

To reproduce using wget:

wget \
 -O hidden.txt \
 --keep-session-cookies \
 --save-cookies cookies.txt \
 https://www.redhat.com/wapps/sso/rhn/login.html?redirect=https%3A%2F%2Frhn.redh
at.com%2Frhn%2FYourRhn.do

hidden=`grep _flowExecutionKey hidden.txt | perl -pe 's/.*value="([^"]+)".*/\1/'`

wget -S -dv \
 --post-data="username=[YOUR RHN USERNAME]&password=[YOUR RHN
PASSWORD]&_flowId=login-flow&_flowExecutionKey=$hidden&_eventId_submit=Log+In" \
 --keep-session-cookies \
 --load-cookies cookies.txt \
 --save-cookies cookies.txt \
 --referer="https://www.redhat.com/wapps/sso/rhn/login.html?redirect=https%3A%2F
%2Frhn.redhat.com%2Frhn%2FYourRhn.do" \
https://www.redhat.com/wapps/sso/rhn/login.html?redirect=https%3A%2F%2Frhn.redha
t.com%2Frhn%2FYourRhn.do

Verify that some cookies such as rh_sso, rh_user and rh_shared_auth have been
saved in cookies.txt, but pxt-session-cookie has not.
