Why would you want to turn the version numbers off? That is what makes the resources cacheable. Since you're on wordpress I'm assuming it's being done by a plugin like W3 Total Cache.

Thanks for the reply Patrick.

So essentially the must-revalidate makes the browser check the asset to see that it hasn't changed, and then only downloads it if it has... but the point is, none of the assets have changed between first and second pass, so why would so many of them need to be downloaded again?

You're correct I am using w3 total cache, but i'm not using that to add versions to the files, i have that option switched off in the settings.
