An access log is a complete list of all the files that were accessed by the visitors of a particular site. Each and every file that was requested for some reason will be listed, so if you have just one webpage with three embedded pics, one video and one embedded text file, as an example, the access log will contain a total of 6 entries - one for any of the 6 files that were accessed when the visitor opened the page. A log usually shows the file name and path, the date, in addition to the visitor’s OS, web browser and IP address. Occasionally you can also find the referrer Internet sites that sent the visitors to your website. The info that an access log file provides is in human-readable plain text format. It can be processed by special software on a personal computer and used to prepare reports on the overall performance of an Internet site, besides the web stats that your web hosting server may have produced.
