This U.S. Government computer system uses software programs to create summary statistics, which are
used for such purposes as assessing what information is of most and least interest, determining technical
design specifications, and identifying system performance or problem areas.
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 /sitename/news/nr012797.html HTTP/1.0" 200 16704 Mozilla 3.0/www.altavista.digital.com
- xxx.yyy.com (or 22.214.171.124) - 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 requestor'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 /sitename/news/nr012797.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.
- 16704 -- 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 this site. Requests for other types of documents use similar information. No other user-identifying information is collected.
