ASP.NET 2 uses XML-based Browser database stored by MS.NET in a
subdirectory of its CONFIG folder, browser.ini being deprecated. Also,
the user can put .browser files (utilizing the same XML format) in
~/App_Browsers and they get compiled whenever the application is
loaded. I plan to work on support for the App_Browsers and the XML
definition files in the near future. Since the definition files are
loaded once during the application startup and whenever a change to any
of the definition files is detected the app is reloaded, we can cache
the database in HttpApplicationFactory.InitType at the cost of using
some more memory. We could keep them in a (generic) SortedList and
populate in such a way where we would not use any wildcard/regex
matches, just full string match. That would probably increase the
