Example of Information Collected For Statistical Purposes

Below is an example of the information collected based on a standard request for a World Wide Web document:

xxx.yyy.com - - [28/Jan/1997:00:00:01 -0500] "GET index.html HTTP/1.0" 200 1928 Mozilla 3.0/www.altavista.digital.com

xxx.yyy.com (or 123.123.23.12)-- this is the host name (or IP address) associated with the requester (you as the visitor). In this case, (....com) the requester is coming from a commercial address. Depending on the requester’s method of network connection, the host name (or IP address) may or may not identify a specific computer. Connections via many Internet Service Providers assign different IP addresses for each session, so the host name identifies only the ISP. The host name (or IP address) will identify a specific computer if that computer has a fixed IP address.

[28/Jan/1997:00:00:01 -0500] -- this is the date and time of the request

"GET index.html HTTP/1.0" -- this is the location of the requested file

200 -- this is the status code - 200 is OK - the request was filled

1928 -- this is the size of the requested file in bytes

Mozilla 3.0 -- this identifies the type of browser software used to access the page, which indicates what design parameters to use in constructing the pages

www.altavista.digital.com -- this indicates the last site the person visited, which indicates how people find our Web pages

Requests for other types of documents use similar information. No other user-identifying information is collected.
