An access log features a record of all the files which have been requested by the visitors while exploring your Internet site. The list is thorough, so when you have a page with 2 embedded images, for instance, all of the three files shall be in the log, not only the page. An access log typically contains the date, the Operating System, the Internet browser and the IP address for each file in human-readable form, so you can get a more complete picture about the hottest files on your Internet site. The log, that's also typically referred to as "raw data", is an addition to the web stats that you normally get with a hosting account, not a substitute. A good example why you may require this sort of a log is if you intend to use some software on your PC to prepare a report about the website’s efficiency, but you don't want to use the standard graphs and tables which come with the server-generated site stats.
