Privacy policy for the Unix Support web server

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.

Logged data

The following table describes the information logged, indexed by the Apache log directive that causes it to be logged.

 

 

DirectiveInformation stored
%h Connecting hostname (may be the name of a web proxy rather than originating client)
%t Time of connection
%r The HTTP request
%>s The status code of the request (success or failure etc.)
%b Number of data bytes sent in response

For example, if a browser on a system with IP address 131.111.11.71 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] 131.111.11.71 "GET /courses/index.html HTTP/1.0" 200 2853
where 200 is the return code meaning "successful transfer" and 2853 is the number of bytes in the web page returned.
