Tracking search engine bots

I am trying to use the “Bot Tracker” plugin to track the bots that index our sites. Since most bots don’t execute the JavaScript, I was trying to use the Image tracking API. Is there a way to pass the User-Agent string or do I need to PHP Client to do this?

unfortuantely you need the PHP client for this at this stage, since it’s a HTTP Header rather than a parameter

Thanks. I will give that a try.
