Blocklist Manager is a simple script designed to download blocklists and
use them to block unwanted website traffic. Blocklists are downloaded
automatically from URLs you specify. Simply upload one file to your web
server, and add one line of code to the top of each page you want to
protect.
03/03/2010 Large blocklists were causing high load times for
pages in which the script was included. Added session
handling to force additional scans to be skipped once
the visitor IP has already been scanned.
Added ASCII encoding for email addresses to reduce
the potential for spam.
02/21/2010 A bug in the initial release caused the script to be
completely non-functional. This bug has been fixed.
Some of the blocklists at iblocklist.com are gzipped.
Added functions to uncompress and add gzipped files to
the local filter file.
