As is the case with most web sites, our web server produces log files that record, for each HTTP request sent to it, the IP address from where our server believes the request came from (which is often the address of an intermediate proxy server), the date and time, the HTTP request itself (command and URL), our server's result code, and the number of bytes transmitted. If a user has logged into our web server, it may also record that user's identity. We may enable the recording of additional data from time to time as the need arises.
This site may store HTTP cookies in your web browser as part of user authentication (login) and to store information needed by other facilities.
As is the case with most web sites, individual pages on this site may contain links to data on other web sites. If your web browser is configured to fetch embedded images, objects or iframes automatically, similar data may be recorded by these other web servers as well as these items are being loaded.
