Introduction

Sometimes in web application development the need arises to show a status message
or similar notices to a user. This can of course be easily done in some success page
but sometimes this page is rendered by a different request because of a redirect.
In these cases you can use some query parameters or similar methods but that's not
always easy to use or might even have security problems.

:mod:`qc.statusmessage` tries to solve this problem by giving you a ``MessageList`` object
which is put into the WSGI environment on ingress and processed on egress to store a list of
messages inside a cookie.
