An access log contains a record of all files which have been requested by the visitors while exploring your Internet site. The list is comprehensive, so if you have a webpage with two embedded images, for instance, all of the three files will be in the log, not only the page. An access log normally features the date, the Operating System, the Internet browser and the IP address for every file in human-readable form, so you can get a more complete picture about the most well liked files on your site. The log, that's also typically referred to as "raw data", is an addition to the web data you commonly get with a hosting account, not a substitute. A good example why you could need this kind of a log is if you would like to use some software on your PC to prepare a report about the website’s functionality, but you don't want to use the typical graphs and tables that come with the server-generated web stats.
