+<h1>CGI<a class="headerlink" href="#cgi" title="Permalink to this headline">¶</a></h1>
+<p>If all other deployment methods do not work, CGI will work for sure.
+CGI is supported by all major servers but usually has a sub-optimal
+performance.</p>
+<p>This is also the way you can use a Flask application on Google&#8217;s <a class="reference external" href="http://code.google.com/appengine/">App
+Engine</a>, where execution happens in a CGI-like environment.</p>
+<div class="admonition-watch-out admonition ">
+<p class="first admonition-title">Watch Out</p>
+<p class="last">Please make sure in advance that any <tt class="docutils literal"><span class="pre">app.run()</span></tt> calls you might
+have in your application file are inside an <tt class="docutils literal"><span class="pre">if</span> <span class="pre">__name__</span> <span class="pre">==</span>
+<span class="pre">'__main__':</span></tt> block or moved to a separate file. Just make sure it&#8217;s
+not called because this will always start a local WSGI server which
+we do not want if we deploy that application to CGI / app engine.</p>

+<h2>Creating a <cite>.cgi</cite> file<a class="headerlink" href="#creating-a-cgi-file" title="Permalink to this headline">¶</a></h2>
+<p>First you need to create the CGI application file. Let&#8217;s call it
+<cite>yourapplication.cgi</cite>:</p>
+<div class="highlight-python"><div class="highlight"><pre><span class="c">#!/usr/bin/python</span>

+<div class="section" id="server-setup">
+<h2>Server Setup<a class="headerlink" href="#server-setup" title="Permalink to this headline">¶</a></h2>
+<p>Usually there are two ways to configure the server. Either just copy the
+<cite>.cgi</cite> into a <cite>cgi-bin</cite> (and use <cite>mod_rewrite</cite> or something similar to
+rewrite the URL) or let the server point to the file directly.</p>
+<p>In Apache for example you can put a like like this into the config:</p>
+<div class="highlight-apache"><div class="highlight"><pre><span class="nb">ScriptAlias</span> <span class="sx">/app</span> <span class="sx">/path/to/the/application.cgi</span>
+</pre></div>
+</div>
+<p>For more information consult the documentation of your webserver.</p>
