Example of information collected by this Web site

Web servers keep a record of their activity in a log file. Every time a visiting computer requests a file from the Web server, a log entry is recorded. A typical log file entry for the National Centers for Coastal Ocean Web site looks like this:

10/04/00 13:19:18 OK 200 somemachine.somenetwork.com Mozilla/4.75 (Macintosh; U; PPC) http://othermachine.othernetwork.com/neatsites.html "oceanservice.noaa.gov" :welcome.html 15208

What this entry means:

• 10/04/00 13:19:18 -- Date and time of the request (24-hour clock).

• OK 200 -- Status code of the request. "OK" and a status code of "200" are equivalent; they mean the requested file was successfully found and delivered to the requesting (visitor's) computer.

• somemachine.somenetwork.com -- Internet address (or IP address, in the form of 123.123.123.123) of the requesting computer. The last part of the address, .com, indicates the requesting computer is on a commercial network. Other commonly seen addresses end in .mil (U.S. military), .net (a different category of commercial network), .org (non-profit organization), .gov (U.S. government agencies, state and Federal), etc. Depending on how the requesting computer is connected to the Internet, this may not identify a specific computer.

• Mozilla/4.75 (Macintosh; U; PPC) -- Type of browser used by the requesting computer.

• http://othermachine.othernetwork.com/neatsites.html -- The Internet address of the last site visited by the requesting computer, useful in discovering how visitors found this Web site.

• "oceanservice.noaa.gov" -- The Internet address of this Web site. As it is possible to operate several Web sites on a single computer, the Web server uses this information to determine which Web site should handle the request.

• :welcome.html -- The name of the file requested by the visiting computer.

• 15208 -- Size of the requested file, in bytes.
