An access log is a complete list of all the files that were accessed by the guests of a particular site. Every file which was requested in some way will be listed, so if you have just one page with 3 embedded graphics, one video and one embedded text file, as an example, the access log shall contain a total of six entries - one for every of the 6 files which were accessed when the visitor opened the webpage. A log normally offers the file name and path, the date, plus the visitor’s Operating System, Internet browser and IP address. In some cases you can also find the referrer sites that sent the visitors to your site. The data which an access log file includes is in human-readable plain text format. It could be processed by special software on a laptop or computer and used to write reports on the performance of an Internet site, independent of the web statistics your web hosting server may have produced.
