An access log is a thorough list of all the files that were accessed by the guests of a given website. Every file which was requested for some reason will be listed, so if you have just one page with three embedded pictures, one video and one embedded text file, as an illustration, the access log shall contain a total of 6 entries - one for every of the 6 files that were accessed when the site visitor opened the page. A log normally contains the file name and path, the date, in addition to the visitor’s Operating System, web browser and IP address. In some cases you may also find the referrer websites that sent the visitors to your Internet site. The data that an access log file includes is in human-readable plain text format. It can also be processed by special software on a laptop or computer and used to write reports on the overall performance of a website, aside from the web statistics your hosting server may have produced.
