Joshua – thank you so much for commenting! I’ll give the new version a go today and update my post. I made the title of this post as neutral as possible because I know projects like this move at such an astonishing rate.

One final question – is the compressed page the module creates cached by it? If not, can mod_deflate be disabled by a configuration flag so Supercache can create a compressed copy of the page once and then serve that?

I totally agree with you that the module complements what Supercache does so I’m really excited to see the day when it’ll work perfectly!
