2. How does it work?

Tags:
The Analyzer reads the information stored in TCP/IP packet headers that are sent from your PC to our server. It does not read your Registry in any way, it simply reads packet headers containing information about your TCP/IP settings. This is the most accurate method we're aware of, since it is OS-independent, and the Analyzer sees what your end actually advertises to external servers (which, in some cases differs from the system configuration).

As the server receives a SYN packet, it extracts the TCP options from it and remembers them, along with the remote port and IP pair. It then continues listening for other packets, which usually arrive (the browser must send at least "GET /" in order to receive any data). Once the browser request is complete, the server sends the simplified web page content, complete with instructions to the Analyzer parser script.
