I host lots of virtual domains. In my opinion, if you haven't got many virtual domains, the best thing is to log each one to a different logfile and analyse them independently. I tried to run analog from my browser, but it didn't work. You can't run analog itself directly from a browser. You need to use the CGI program which outputs the correct HTTP headers.
People are more familiar with the country codes.
And not all of my languages have language codes anyway. I didn't write analog for the money, and I'm happy just to see people use it. I haven't got time to support it commercially, and I can't use my academic account for commercial purposes. Also, by making it freeware, lots of people send me ideas and code to include in future versions.
