Hi all, I require Monks Wisdom it trying to detect Web server abuse and prevent robot like page access.
Detection is to be done on a web server's Access_LOG file, with entries like 
200.1.1.62 - - [31/Dec/2007:01:21:42 -0500] "POST /cgi-bin/idb/1.0/por
+tal/adduser.cgi HTTP/1.1" 200 4266
200.1.1.62 - - [31/Dec/2007:01:21:43 -0500] "GET /idb/1.0/html/portal/
+cust.css HTTP/1.1" 304 -

[download]

Say like more than 200 access/hour from a particular IP, detect alphabetic site access etc. Please guide me on how to accomplish this task and if possible sample codes or articles concerning this.

Thank you in advance.
