I've just pushed memcachablehandler to GitHub, which is a small Python App Engine library to make it easy to memcache pages - or images, or anything else you might serve up - and re-serve them without having to regenerate them from a Django template or suchlike. This should speed up response times ever so slightly, and also maybe make things more reliable as well (based on my personal experience with the memcache vs datastore availability).
The library is a slightly-tweaked version of some of the code that I've had in this blog for the past few days, so hopefully it's not too buggy. I know I'm not the first to write something like this - see the README for a link to something similar - but maybe it could come in useful to someone else?
I don't currently have any plans to extend the functionality beyond what's already there, but anything that gets updated in this blog should get pushed into that repo in fairly short order. At some point I'll probably make this blog code public as well, but I want to get it in a much more polished state before daring to show it to the world :-)
