<p>Certain things are common enough that the chances are high you will find
them in most web applications. For example quite a lot of applications
are using relational databases and user authentication. In that case,
chances are they will open a database connection at the beginning of the
request and get the information of the currently logged in user. At the
end of the request, the database connection is closed again.</p>
<p>There are more user contributed snippets and patterns in the <a class="reference external" href="http://flask.pocoo.org/snippets/">Flask
