Re: sessions

Really? Your IP randomly changes when your surfing between say yahoo.com and msn.com does it? While it is true that you can force an IP change while your connected, I have not yet seen a provider which randomly decides to change your IP address in the middle of your surfing, if your talking about DHCP IP's on say Cable or ADSL modem's, then I can understand what your saying, but even then the IP change is almsot always at times when your computer is turned off or restarted. I have been using an extra IP check in our sessions on a website which get's somewhere in the area of 500,000 unique hits a month and we have not had a single complaint of people's session's being dropped.
