An access log is a complete list of all the files which were accessed by the visitors of a given Internet site. Every single file that was requested in some way will be listed, so if you have one webpage with 3 embedded pics, one video and one embedded text file, for example, the access log shall contain a total of six entries - one for every of the 6 files which were accessed when the visitor opened the webpage. A log usually contains the file name and path, the date, in addition to the visitor’s OS, web browser and IP address. Sometimes you could also find the referrer Internet sites that sent the visitors to your website. The info that an access log file contains is in human-readable plain text format. It may be processed by special software on a personal computer and used to write reports on the performance of a website, independent of the web stats your hosting server may have generated.
