Is there a way to determine a site visitors browser type and then based on the determination, force them to view a certain theme? I am working on a new theme and, because of IE6s lame handling of standards, doesn't output correctly in IE6. IE6 amounts for about 20% of my user base so recoding the site is almost not worth it. I'd like to determine who is using IE6 and below and force them to my current theme (which works) and just add a note about what they are missing. Is this possible? Thanks.
