I'd like to bring up one another (small) point. Virtually all banner advertising on the web relies on redirects for click-throughs so that click rates can be measured. This means that the redirection to the advertiser's web site will always be an unverifiable transaction. So, when a user visits an advertiser's site directly, cookie assignment on the home/jump page is possible, whereas when the user visits the page via an advertisement, it will not be possible. Designers of web sites (at least the large percentage who will advertise on the web) will have to take into account that cookie assignments on their home page may fail a large percentage of the time. If they wish to measure number of unique visitors to their site, they will get a highly inaccurate reading since often multiple cookies will be assignied to a single user before one "sticks". This is not a major flaw, but it is inelegant, and I just want to make sure everyone has considered this. Dwight
