Getting Browser and Version Using Coldfusion

Is there something built into Coldfusion that will let me know the browser and version number of the surfing site on my site? Are there any existing libraries that will allow me to do this?

My google-fu did not have many other things besides the simple ones if there were instructions defining IE.

I did a reset of the cgi.http_user_agent variable in Chrome:

Mozilla / 5.0 (Windows NT 5.1) AppleWebKit / 534.24 (KHTML, e.g. Gecko) Chrome / 11.0.696.77 Safari / 534.24

There are three different browsers mentioned there! Doing if if look for or will return true. Should there be a more formal approach?

Here is a recent build of the name and version of the browser. Tested on Opra / IE 8 / IE 9 / IE 10 / IE 11 / Edge / Chrome / Firefox
