For a while I've been hearing about using nginx as a reverse proxy front end to Apache to handle the static content. After doing a bit of fiddling about with it this week I wrote a quick how to blog describing how I set it up and some of the rational for doing such. It seems to work quite nicely, but suspect it'd need a bit more tweaking for sessions and other more complicated php stuff.

If anyone has any observations, suggestions or corrections to offer I'd be interested to hear them.
