<p>Werkzeug is intended to be a utility rather than a framework. Because of that
the user-friendly API is separated from the lower-level API so that Werkzeug
can easily be used to extend another system.</p>
<p>All the functionality the <code class="xref py py-class docutils literal"><span class="pre">Request</span></code> and <code class="xref py py-class docutils literal"><span class="pre">Response</span></code> objects (aka
the “wrappers”) provide is also available in small utility functions.</p>
<div class="section" id="example">
<h2>Example<a class="headerlink" href="#example" title="Permalink to this headline">¶</a></h2>
<p>This example implements a small <cite>Hello World</cite> application that greets the
user with the name entered:</p>

objects but by taking advantage of the parsing functions werkzeug provides:</p>

<h2>High or Low?<a class="headerlink" href="#high-or-low" title="Permalink to this headline">¶</a></h2>
<p>Usually you want to use the high-level layer (the request and response
objects). But there are situations where this might not be what you want.</p>
<p>For example you might be maintaining code for an application written in
Django or another framework and you have to parse HTTP headers. You can
utilize Werkzeug for that by accessing the lower-level HTTP header parsing
functions.</p>
<p>Another situation where the low level parsing functions can be useful are
custom WSGI frameworks, unit-testing or modernizing an old CGI/mod_python
application to WSGI as well as WSGI middlewares where you want to keep the
overhead low.</p>
