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 /news/nr012797.html HTTP/1.0"
200 16704 Mozilla 3.0/www.altavista.digital.com
- xxx.yyy.com (or 184.108.40.206)-- 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
- [28/Jan/1997:00:00:01 -0500] -- this is the date and time of the request
- "GET /news/nr012797.html HTTP/1.0" -- this is the location of the requested
file on the web server 200 -- this is the status code - 200 is OK - the request
- 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 our site
- Requests for other types of documents use similar information. No personally-identifying
information is collected.
