This web server maintains logs of all requests made to it. These logs are kept for the purposes of system administration, bug tracking and usage statistics. The information is kept for 14 days on disc and for no longer than a further 14 days on the backup tapes.
Relevant subsets of this data may be passed to computer security teams as part of investigations of specific attacks involving the web server. Otherwise the logged information is not passed to any third party except where required by law.
Please note that a log is a record of what a server sees, not necessarily what was initially sent. If a request is sent via a proxy the log file will show the proxy's address. If someone has forged your address the log file will show your address.
||Connecting hostname (may be the name of a web proxy rather than originating client)|
||Time of connection|
||The HTTP request|
||The status code of the request (success or failure etc.)|
||Number of data bytes sent in response|
For example, if a browser on a system with IP address
184.108.40.206 asked for the URL
http://www-uxsup.csx.cam.ac.uk/courses/index.html at 12:25 on the 15th of February the line in the log file would be
[15/Feb/2001:12:25:00 +0000] 220.127.116.11 "GET /courses/index.html HTTP/1.0" 200 2853
200 is the return code meaning "successful transfer" and
2853 is the number of bytes in the web page returned.
