WSGIFilter is a framework (in the form of an abstract base class) for building output-filtering WSGI middleware.
It can be installed from the subversion repository with easy_install WSGIFilter==dev
Here are some key features of "WSGIFilter":
· You can filter just some content types (e.g., text/html) with low overhead for unfiltered output.
· Handles issues of decoding and encoding responses using the HTTPEncode system of formats.
· Does all the hard stuff with WSGI output filtering.
