Hi Ellen

Perhaps you haven't heard of the Brumleve cache bug, or the other various
ways remote websites can gather the information in your browser's history.
It is so simple to use POST instead of GET... I don't see why you want to
take the chance of it being intercepted.  There are a number of ways that
requested URLs can be logged etc.

Hi,

Please allow me to introduce myself.  My name is Ellen O'Rourke and I am
Host Member Manager for ValueClick.

I would like to refer to the letter you wrote BUGTRAQ () NETSPACE ORG
regarding "ValueClcik vernerability."

Let me explain:

If the user decides to go to another site after they
are logged in,  either via a bookmark or typing in
a url, the referring url will be blank.  If we had
a link to the outside, the referring url would
contain the logged in user's username and password.

The links that we do have to the outside, such
as on the exclude banners page where a user
can click on a banner to view the advertiser's
site, have the referring url stripped off to
protect the host's login info.

If you have evidence that contradicts this, we would very much appreciate
your advising us.
