An access log is a comprehensive list of all the files which were accessed by the guests of a particular site. Each and every file that was requested for whatever reason will be listed, so if you have a single page with three embedded graphics, one video and one embedded text file, as an illustration, the access log will contain a total of 6 entries - one for each of the 6 files which were accessed when the website visitor opened the webpage. A log typically offers the file name and path, the date, along with the visitor’s OS, Internet browser and IP address. Oftentimes you could also find the referrer sites that sent the visitors to your Internet site. The data an access log file contains is in human-readable plain text format. It can be processed by special software on a personal computer and used to prepare reports on the functionality of a website, in addition to the web stats that your server may have created.
