+        <h2>Description:</h2>
+        <p>
+            This processor starts an HTTP server and creates a FlowFile for each HTTP Request
that it receives. The Processor leaves
+            the HTTP Connection open and is intended to be used in conjunction with a 
+            <a href="../org.apache.nifi.processors.standard.HandleHttpResponse/index.html">HandleHttpResponse</a>
Processor.
+        </p>
+        
+        <p>
+        	The pairing of this Processor with a <a href="../org.apache.nifi.processors.standard.HandleHttpResponse/index.html">HandleHttpResponse</a>
Processor
+        	provides the ability to use NiFi to visually construct a web server that can carry
out any functionality that is available
+        	through the existing Processors. For example, one could construct a Web-based front
end to an SFTP Server by constructing a
+        	flow such as:
+        </p>
+        
+        <p>

+        </p>
+        
+        <p>
+        	The HandleHttpRequest Processor provides several Properties to configure which methods
are supported, the paths that are
+        	supported, and SSL configuration. The FlowFiles that are generated by this Processor
have the following attributes added to
+        	them, providing powerful routing capabilities and traceability of all data:

+        	This Processor must be configured with the same &lt;HTTP Context Map&gt;
service as the corresponding HandleHttpRequest Processor.
+        	Otherwise, all FlowFiles will be routed to the 'failure' relationship.
+        </p>
+        
+        <p>
+        	All FlowFiles must have an attribute named <code>http.context.identifier</code>.
The value of this attribute is used to lookup
+        	the HTTP Response so that the proper message can be sent back to the requestor.
If this attribute is missing, the FlowFile
+        	will be routed to 'failure.'
