An access log is a comprehensive list of all the files which were accessed by the visitors of a certain Internet site. Any file which was requested in some way will be listed, so if you have only one webpage with three embedded pics, one video and one embedded text file, as an example, the access log will contain a total of six entries - one for any of the six files which were accessed when the website visitor opened the webpage. A log usually offers the file name and path, the date, in addition to the visitor’s Operating System, worldwide web browser and IP address. Sometimes you may also find the referrer sites that sent the visitors to your Internet site. The info that an access log file contains is in human-readable plain text format. It may be processed by special software on a laptop or computer and used to write reports on the efficiency of an Internet site, besides the web stats that your web hosting server may have produced.
