title: IIB Flow with HTTP Input Node at beginning returns "Unsupported Method: GET"
body: <p>I have a flow in IBM Integration Bus (IIB) which has a HTTP Input as it's entry node.  I am running this flow on a local Integration Node.  When I deploy the BAR file containing this flow and then attempt to initiate the flow by entering the proper URL in a browser I get an "Unsupported Method: GET" response.  The path suffix for the HTTP Input node is "/startTestFlow".  The complete URL entered in the browser is "<a href="http://localhost:7800/startTestFlow" rel="nofollow noreferrer">http://localhost:7800/startTestFlow</a>".  I attempted to post the same URL in Postman and it got the same response.  That tool at least allowed me to examine the response headers.  They were:</p>
  
  <pre><code>Allow →POST, HEAD, OPTIONS
  Connection →close
  Content-Length →24
  Date →Tue, 26 Sep 2017 20:51:50 GMT
  Server →Apache-Coyote/1.1
  </code></pre>
  
  <p>So the response clearly does not list GET as an approved request method.  The question from me is why and where would this limitation be coming from?</p>
