From last week via @Sathya:

How much information can websites get about your browser/PC?

Does anyone know of any other sites that will be able to get more information from the user passively like this? I'm not talking about port-sniffing or any kind of interaction from the user, just the info that a server can get from a 'dumb' visit.

  • Specifically it can request the browser and version. It can also usually get the monitor resolution info. These are transmitted so the site can change to provide you the best experience. I should be able to also get your IP address so it should be able to geographically (roughly) locate you. If it blips a SSL type connection request, it should also be able to get what encryption you support. I remember there were MANY other things it can request. There used to be sites that you could go to that would spit back all the info it could get on you based on a single connection, but I can't remember Commented Sep 18, 2012 at 21:36
  • It can also get basic OS info as I recall. Commented Sep 27, 2012 at 11:30
