<h1>Anatomy
 
 paulb@347     10 
of a WebStack
 
 paulb@347     11 
Application</h1>
 
 paulb@347     12 
<p>The simplest way to think of a
 
 paulb@347     13 
Web application is as just some code which
 
 paulb@347     14 
sits on a server and is sent messages - specifically HTTP requests - to
 
 paulb@347     15 
which it must respond by writing out messages to send back -
 
 paulb@347     16 
specifically HTTP responses. When using WebStack, we think of the
 
 paulb@347     17 
situation in terms of&nbsp;the following components:</p>
