An access log is a complete list of all the files that were accessed by the visitors of a given Internet site. Every file which was requested for whatever reason will be listed, so if you have only one page with 3 embedded images, one video and one embedded text file, as an illustration, the access log shall contain a total of six entries - one for each of the 6 files which were accessed when the site visitor opened the page. A log typically shows the file name and path, the date, as well as the visitor’s Operating System, web browser and IP address. In some cases you can also find the referrer websites that sent the visitors to your website. The information 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 functionality of an Internet site, in addition to the web statistics your server may have generated.
