AutoPrefix Support

Does WebOptimizer Support AutoPrefixing, trying to get it link up correctly and i have found references to it around the web, though nothing concrete about if or how to get it to work:

I also found a previous request for information that was closed without response: #14

Does anyone have knowledge or experience in getting this to work?
