An access log is a detailed list of all the files which were accessed by the visitors of a certain site. Every single file that was requested for some reason will be listed, so if you have a single page with 3 embedded pictures, one video and one embedded text file, as an illustration, the access log shall contain a total of six entries - one for every of the six files that were accessed when the site visitor opened the page. A log typically contains the file name and path, the date, plus the visitor’s Operating System, Internet browser and IP address. Occasionally you may also find the referrer Internet sites that sent the visitors to your website. The information an access log file provides is in human-readable plain text format. It can also be processed by special software on a laptop or computer and used to prepare reports on the overall performance of a site, in addition to the web stats which your hosting server may have generated.
