I just noticed a new and quite neat feature in R2:

In admin mode (admin/default.aspx) you now get separate cache information for each Page Provider.

Here is a screenshot of my local site where I have the UKTop40 PageProvider installed.

If you look closely you might notice that there is something odd about the numbers in the statistics overview.

There is a bug

I followed Johan's cache example and implemented caching for my PageProvider. The cache hit rate increased, but "Pages delivered from cache" was stuck on cero - I started wondering if I had any caching at all.

 So, the real cool thing is that we now have separate caching statistics for Page Providers, but we have to wait just a little bit more to get real updated values. Don't worry, the pages are cached, we just can't see it in the statistics yet.
