 <a href="http://w3techs.com/technologies/cross/web_server/ranking">second most common web server among the top 100,000 websites</a>. Nginx also functions well as a 
 reverse proxy to handle requests and pass back responses for Python

+<h2>How is Nginx used in a Python web app deployment?</h2>
+<p>Nginx is commonly used as a web server to serve static assets such 
+as images, CSS and JavaScript to web browser clients. </p>
+<p>Nginx is also typically configured as a reverse proxy, which passes 
+appropriate incoming HTTP requests to a <a href="/wsgi-servers.html">WSGI server</a>.
+The WSGI server produces dynamic content by running Python code. When the 
+WSGI server passes its response, which is often in the HTML, JSON or XML 
+format, the reverse proxy then responds to the client with that result. </p>
+<p>The request and response cycle with a reverse proxy server and the WSGI
+server can be seen in the following diagram.</p>

+<p>Typically the client will not know or need to know that a Python web 
+application generated the result. The result could have instead been 
+generated by one or more backend systems written in any programming language,
+not just Python.</p>
