As is the case with most web sites, our web server www.cl.cam.ac.uk 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. Such logins may be verified via the University of Cambridge Raven authentication service. We may enable the recording of additional data from time to time as the need arises.
All data is available to the server's administrators and will be used primarily to monitor the server's performance, to optimize the content of our web site, and to detect malfunctions or malicious behaviour. Log files may also be made available to other members of the Computer Laboratory or Computing Service, for similar purposes and for use in research projects. We may keep our log files indefinitely. Our detailed log files are not normally available to anyone outside the University of Cambridge Computer Laboratory or Computing Service, unless we are required to transfer such data by UK law. We may publish summary statistics generated from our web-server logs, which do not contain information related to individual users.
