My blog engine is nothing if not a work in progress. Recently I've been tinkering with the page caching. I've made a few tentative changes that are now live; please let me know if you encounter any breakage. The update caches more pages and uses more tightly scoped cache invalidations less frequently. I guess that's a long way of saying "better caching".

Very soon I'll write a post detailing all the interesting bits ticking away inside my blog engine. Stay tuned!
