A new version of Teapot was released: Teapot 0.9
It still less than 700 Lines of code and a nice micro web framework for Pharo.
You need to load "ConfigurationOfTeapot-AttilaMagyar.6", if you are on Pharo 4 you can directly load it
from the configuration browser.
As this framework is very easy to use (it bases on the concept of URL routes): you can serve dynamic or static HTML pages,
JSON and other web related stuff easily from Pharo. It is nice especially if frameworks like Seaside are too heavy for your web application needs.
