title: Using <c:import> with method post doesn't work
body: <p>I have a file form.jsp with a form, that submit to test.jsp.</p>
  
  <p>form.jsp</p>
  
  <pre><code> &lt;form id="formTest" action="test" method="post"&gt;
       &lt;input type="text" /&gt;
       &lt;input type="submit" value="send"/&gt;
   &lt;/form&gt;
  </code></pre>
  
  <p>test.jsp</p>
  
  <pre><code>    &lt;p&gt;  this is a test&lt;/p&gt;
       &lt;c:import url="/anotherpage" /&gt;
  </code></pre>
  
  <p><br/>
  I'm using SpringMvc. Here is the controller:</p>
  
  <pre><code>@RequestMapping(value="/form", method=RequestMethod.GET )
     public String form(){... }
  
  @RequestMapping(value="/test", method = RequestMethod.POST )
     public String test(){ ... }
  
  @RequestMapping(value="/anotherpage", method = RequestMethod.GET )
     public String anotherpage(){ ... }
  </code></pre>
  
  <p>When submit button is clicked, the tag <code>&lt;c:import url="/anotherpage" /&gt;</code> does not work. However 
  if i change the method to get :<code>@RequestMapping(value="/test", method = RequestMethod.GET )</code></p>
  
  <p>and </p>
  
  <pre><code> &lt;form id="formTest" action="form" method="get"&gt;
  </code></pre>
  
  <p>it works correctly.</p>
  
  <p>Why <code>&lt;c:import url="/anotherpage" /&gt;</code> only work with method GET?</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>I'm using:</p>
  
  <pre><code>&lt;%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%&gt;
  </code></pre>
