WebCheck
WebCheck is a small program which checks web sites for changes and notifies about modified webpages by mail. It's written in Python and is free software released under the GNU General Public License (GPL).It also integrates with Microsoft Internet Explorer. Simply create internet favorites into a webcheck folder and WebCheck monitors them.
Finally it is possible to specify regular expressions for filtering parts of constantly changing webpages.
Algorithm
WebCheck doesn't store copies of the monitored web pages. It retrieves each checked page, skips all html markup leaving only plain text, reduces multiple whitespace characters to one single blank and computes a crc checksum of the resulting string. Only this checksum needs to be stored.
Requirements
- Python 2.2 or later
- Modified smtplib.py for smtp server using authentification
- timeoutsocket.py
- webcheck.py
