A colleague on campus was finally able to explain why turning on Content
Advisor in Internet Explorer broke our IMP. He even suggested a fix
that turned out to be correct. He used Ethereal to watch an imp session.
Content Advisor checks the Document Root of the site for rating
information with a "GET /" request. When Horde or IMP are the root of
the site this request is redirected and begins a new session. The "GET
/" request needs to use the session cookie already assigned. The problem
is solved by changing the cookie_path in horde/config/registry.php from
"/horde" to "/".
Searching for "cookie path" in the IMP list demonstrates that this
information is well known for virtual hosting. The Content Advisor
symptoms just haven't been attached to it.
The users who have had these problems don't run Content Advisor but they
probably have some sort of spyware/adware that acts similarly.
My thanks go to Sergey Kanareykin who solved this problem for me.
I have run into this as well. I've found that
enabling IE's content advisor will cause this
behavior. Very few machines have this turned on so
that's why you are seeing such a low percentage of it
and is also why it doesn't happen when they try
another computer. I don't have a solution for you
though (only a note of it on my "Known Issues" page).
I did post this a while ago, but I really didn't go
into it much since I just found it at the time (and
I'm not going into it here either cause I still don't
know much about it ;). Here's my favorite response to
> Well, IMP is known for its explicit language. ;-)
Not much help, but gave a good laugh after a
frustrating day. ;)
Hope this gives you some sort of lead. Good luck,
