GET: /indexfr.php
HOST: www.seo.fr
USER_AGENT=Mozilla/4.0 (compatible; MSIE 6.0; Windows XP; FREE)
REFERRER=http://www.google.com/search?hl=fr&q=analyse+d%27audience&lr=
REMOTE_ADDR=255.64.12.01
GET contains the name of the web page you want to see (in this example index.php)
HOST contains the name of the site where this page is located
USER_AGENT is the “signature” of your browser (in this example Internet Explorer 6, under windows XP, connected by free.fr)
REFERRER is the site from which you came (in this example, you launched a search on Google before accessing the seo.fr site)
REMOTE_ADDR is your IP address
The server of site loads (for HTML sites) or generates (for PHP sites) the page you request as soon as it receives this HTTP request. After this it sends back to your browser, which displays it: you can then read it.
It also makes it possible to recognize an indexing robot if the IP address makes it possible to determine in which country the visitor is located. Some sites keep an updated list of the IPs of the main indexing robots to facilitate their detection by the cloakers.
