Has anyone done any analysis (or know where I can find some!) on what proportion of internet users are using a browser/operating system combination that support SNI (Server Name Indication) SSL/TLS certificates?
I know for example that IE on XP doesn't support this, and that older versions of OSX also don't.
I know that there's no such thing as a 'typical' user, and that each site has a different profile, but I'm looking for some kind of order of magnitude view of how common these configurations are these days to help the decision making process along a bit for a new site I'm looking to deploy.
If you do provide specific figures or references to analysis, could you add the date to your answer too? Just so that other people looking at this question in the future have an idea of when that information was current, as I'd expect it to shift over time...
