I've updated Pyplate again. This time the UI hasn't changed much, but I've done a lot of work under the hood. I've added a bunch of fixes which should make Pyplate much more secure.
I've also switched moved away from CGI amd updated Pyplate to use WSGI. This has made a huge difference to the page load time of dynamic pages. Performance with static pages hasn't really changed.
There's now a simple web server supplied with Pyplate. It's a little slower than Nginx...
