An access log is a detailed list of all the files that were accessed by the visitors of a certain website. Every file that was requested for whatever reason will be listed, so if you have just one page with 3 embedded pics, one video and one embedded text file, as an example, the access log shall contain a total of six entries - one for any of the six files that were accessed when the visitor opened the webpage. A log usually shows the file name and path, the date, as well as the visitor’s Operating System, web browser and IP address. Sometimes you may also find the referrer sites that sent the visitors to your website. The information an access log file includes is in human-readable plain text format. It may be processed by special software on a laptop or computer and used to prepare reports on the functionality of an Internet site, aside from the web stats which your hosting server may have produced.
