I remember having seen somwhere that it is possible to tell where a user came from to a website. More specifically, I want to determine the (Google etc.) search that led to my site. How can I do that?
As far as I know the HTTP protocol, nothing like this is sent to the server in a GET request, so I also wonder how it is done technically.
sign up for google analytics for free to get those statistics and a whole lot more. Seeing where someone came from is done by checking the http referer header.
