The TurboGears/CherryPy application server for this blog engine is now running behind a nginx reverse proxy on a name-based virtual host. This has several advantages:

• Static files can be served faster by nginx.
• I can have CherryPy running on any port and nginx will forward it transparently.
• I can still use nginx as a normal web server at the default virtual host address.

I also plugged in a CherryPy filter that sets Last-Modified and Expires headers on all responses. Of course, this still needs to be fine-tuned, so if you seem to be getting old pages, just hit Shift-F5 (IE) or Control-R (Firefox) to get a fresh copy of a page.
