Server logs

At every HTTP request, the server saves a line in the server log containing the request time, the IP address, the user agent, the referrer, the request address and method, and the result status.

The data is used for tracking of possible security issues and for traffic statistics.


On some pages of this website, Google reCAPTCHA is used to determine whether the visitor is a human or not. By using reCAPTCHA, Google may receive information about the IP address, user agent and other information about the hardware and software. Google may also save cookies in your browser.
