<div class="block">Defines a set of methods that a servlet uses to communicate with its servlet
container, for example, to get the MIME type of a file, dispatch requests, or
write to a log file.
<p>
There is one context per "web application" per Java Virtual Machine. (A
"web application" is a collection of servlets and content installed under a
specific subset of the server's URL namespace such as <code>/catalog</code>
and possibly installed via a <code>.war</code> file.)
<p>
In the case of a web application marked "distributed" in its deployment
descriptor, there will be one context instance for each virtual machine. In
this situation, the context cannot be used as a location to share global
information (because the information won't be truly global). Use an external
resource like a database instead.
<p>
The <code>ServletContext</code> object is contained within the
<a href="../../javax/servlet/ServletConfig.html" title="interface in javax.servlet"><code>ServletConfig</code></a> object, which the Web server provides the servlet when
the servlet is initialized.</div>

This method allows the servlet container to make a resource available to

The servlet container must implement the URL handlers and

The resource content is returned directly, so be aware that requesting a
