Webmasters: you can DETECT when surfers have Zango installed

I saw it posted on another board that Zango shows up in the user-agent line that browsers send to the web server when they fetch an object. Did a test and sure enough it is there. Some examples:

Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; .NET CLR 1.1.4322; ZangoToolbar 4.8.2)
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; ZangoToolbar 4.8.2)
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; ZangoToolbar 4.8.2)
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; YPC 3.2.0; .NET CLR 1.0.3705; .NET CLR 1.1.4322; .NET CLR 2.0.50727; ZangoToolbar 4.8.2)
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; ZangoToolbar 4.8.2)

This means you can check if "ZangoToolbar" is present in the Apache HTTP_USER_AGENT field and redirect to a page explaining why, and how to uninstall Zango.

So far 0.4% of my uniques are showing as having Zango installed.
