An access log is a text file containing a complete report on all the files accessed by your Internet site visitors. All of the files which were requested in one way or another shall be included, so if you have a PHP script app and a visitor opens just the home page, for instance, you might find numerous files inside the log. It is because there are components on the home page that are embedded - parts of other Internet pages, graphics, and so on. These files shall be listed within the access log, so you're able to get a full picture of the way your website works. The data is in plain text format, so the logs are frequently described as "raw data" too. An access log contains the name of each and every requested file, the path to it, the date it was accessed, along with the user’s IP address, world-wide web browser and OS. More info, including the referrer website, is typically included as well. A log file may be processed by various desktop applications for statistical purposes as an addition to the web statistics created by your server.
