Description / purpose
This plugin rewrites with JavaScript the comments form’s "action" value from the well-known wp-comments-post.php to a randomized script name. With the help of Apache’s mod_rewrite module the URL got rewritten to point back on wp-comments-post.php. The code got extracted from the script’s name and submitted as a GET variable. So the plugin is now be able to block POST requests only on wp-comments-post.php and keep your weblog a little more spam-free. 🙂

Features
Here is a list of the current features of my plugin:

• Several data can be added or removed from the final key generation process in the settings section.
• Blocks attempts on the vanilla wp-comments-post.php but accepts POST requests on e.g. wp-comments-post-random-code-here.php.
• Simple installation: Upload one file and add lines to the .htaccess file.
• Works with WordPress 2.x.

Requirements

• WordPress 2.0.4 (cause of many fixes!)
• And all requirements WordPress needs
