This module handles sending static content such as in-memory data or
files. At this time it has cache helpers and understands the
if-modified-since request header.
Depreacted: pylons.database will be removed from a future version of
Pylons. SQLAlchemy 0.3.x users are recommended to migrate to SAContext
(http://cheeseshop.python.org/pypi/SAContext) for similar functionality.
