Indeed - the response status guard was added slightly later so I never thought to merge the two!

So, this snippet caches the full page/reponse based on how long it takes to load.
Is that right?

maikeldaloo: not quite, it caches the full response based on how busy the server is at the time.

However, factoring in page build time isn't such a bad idea!

That's really cool.

Just noticed a tiny bug when developing locally on a Windows machine, and possibly if the site is hosted on a Windows machine.

Windows doesn't allow semicolons (:) in file names.
It's better to use a dash or an underscore.

Solution: don't develop on windows ;)

I've update the gist to fix this anyway.

Haha, I love my Windows :)
Thanks.
