<h1>Web Servers</h1>

<p>Web servers respond to

<a class="reference external" href="http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol">Hypertext Transfer Protocol (HTTP)</a>

requests from

clients. A client is usually a browser such as Internet Explorer, Firefox,

or Chrome, but it can also be a</p>

<li>headless browser, which is commonly use for testing, such as

<a class="reference external" href="http://phantomjs.org/">phantomjs</a></li>

<li>commandline utility like <a class="reference external" href="https://www.gnu.org/software/wget/">wget</a>

or <a class="reference external" href="http://curl.haxx.se/">curl</a></li>

<li>a text-based web browser such as

<li>web crawler.</li>

</ul>

<p>Web server process requests from the above clients. The result of the web

server's processing is a

<a class="reference external" href="https://developer.mozilla.org/en-US/docs/HTTP/Response_codes">response code</a>

and commonly a content response. Some status codes, such as 204 (No content)

and 403 (Forbidden), do not have content responses.</p>

<p>In a simple case, the client will request a static asset such as a picture

or JavaScript file. The file sits on the file system in a location the

web server is authorized to access and the web server sends the file

to the client with a 200 status code. If the client already requested the

file and the file has not changed, the web server will pass back a 304

"Not modified" response indicating the client already has the latest version

of that file.</p>

<p>A web server sends files to a web browser based on the web browser's

request. In the first request, the browser accessed the

"www.fullstackpython.com"

address and the server responded with the index.html HTML-formatted file.

That HTML file contained references to other files, such as style.css and

script.js that the browser then requested from the server.</p>

<p>Sending static assets (such as CSS and JavaScript files) can eat up a

large amount of bandwidth which is why using a Content Delivery Network

(CDN) is important when possible (see the content delivery network

section for a more detailed explanation).</p>
