An access log is a complete list of all the files which were accessed by the guests of a particular site. Every file which was requested for some reason shall be listed, so if you have only one page with three embedded graphics, one video and one embedded text file, as an example, the access log will contain a total of 6 entries - one for each of the 6 files that were accessed when the website visitor opened the webpage. A log normally offers the file name and path, the date, as well as the visitor’s OS, Internet browser and IP address. Occasionally you can also find the referrer websites that sent the visitors to your Internet site. The information which an access log file features is in human-readable plain text format. It can also be processed by special software on a desktop machine and used to write reports on the overall performance of a site, in addition to the web stats that your hosting server may have created.
