inMemoryHtmlCache seems to be broken

[lammertw]

I've been trying to get the inMemoryHtmlCache to work. It doesn't seem to work at all. After a little bit of debugging it does not seem to share a single cache between all workers. And even worse, it appears to create a separate cache for the beforePhantomRequest and afterPhantomRequest functions. Therefore the page being caches in afterPhantomRequest can never be read from the beforePhantomRequest function.

Looks like I didn't correctly update that when we switched to the multi-process version of Prerender. I'll look at fixing it soon.

Thanks for letting me know!
