Blocking Bad Bot User Agents

 
Aug 13, 2003

Here's an article with some code to block user bots that may scan your site for content or for email addresses to spam. While the code here was written specifically for Apache, it is possible to do the same thing in ColdFusion by simply detecting the value of the CGI variable HTTP_User_Agent. This article is more relevant today than when it was published, as before the current virus attack (see our coverage in Security), there was a sighting of bots scanning through web pages looking for email addresses.
