Extend the Visitor Maps and Who’s Online plugin by Mike Challis with this handy plugin. This plugin adds additional features, such as IP and referer banning. It also alters the Referer column for the Admin’s Who’s Been Online grid, displaying the referring host name followed by the search string, if there is one. Referer links are proxified so you can click them without exposing your referring address. Long URLs are prevented from expanding the Who’s Been Online grid too wide for viewing. This plugin writes to .htaccess, which is automatically backed-up before any changes are made. There are no settings required.
This plugin is available for download for your site.
