Log-reader is a Scripts software developed by DevDaily Interactive, Inc.. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Log-reader:

The log-Reader.cgi program is designed to operate as a Perl/CGI program. It reads the Apache access_log file in standard ECLF format, interprets the records in this file, and returns (a) the most popular URL's on your web site and (b) the top TCP/IP addresses of clients who visited your web site.

With this information, you can determine which URL's on your site are popular, and who they appeal to. You can also tell if somebody has been spidering your web site by looking for uncommonly high numbers of hits from one web site address.
