I don't think firebug counts the initial request to fetch the host page, so two requests. One for the nocache.js and another for the cachable HTML. With the inlining of the nocache.js file, you could get it down to 0 requests if the retrieved page is cached forever. Are you saying to inline the generated JS in the host page too? How could you do that? Don't you need the selector script to pick the correct compiled version? Maybe I'm just not understanding what you mean. > 2 requests is very impressive, Arthur!

Thanks Bruce!
