An access log is a detailed list of all the files that were accessed by the guests of a given Internet site. Any file which was requested in some way shall be listed, so if you have only one page with three embedded images, one video and one embedded text file, as an illustration, the access log shall contain a total of 6 entries - one for each of the six files which were accessed when the visitor opened the webpage. A log usually shows the file name and path, the date, plus the visitor’s OS, worldwide web browser and IP address. Oftentimes you may also find the referrer websites that sent the visitors to your site. The info which 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 prepare reports on the functionality of a site, in addition to the web stats which your server may have generated.
