This little program can make an access log for certain pages, and the log file can be analyzed by other log analyzing software. If you want to get the combined format log with referer and user agent information, or you want to know the referer information of certain pages, but your hosting provider doesn't offer access log downloading, or just provide the common format log, then you can use this program.
