title: How can I post parameters for JSTL import tag (<c:import>)?
body: <p>I'm currently using JSTL  tag in a JSP page to import the content of an external page:</p>
  
  <pre><code>&lt;c:import url="http://some.url.com/"&gt;
     &lt;c:param name="Param1" value="&lt;%= param1 %&gt;" /&gt;
     ...
     &lt;c:param name="LongParam1" value="&lt;%= longParam1 %&gt;" /&gt;
  &lt;/c:import&gt;
  </code></pre>
  
  <p>Unfortunately the parameters are now getting longer. Since they are encoded as <strong>GET</strong> parameters in the URL, I am now getting "414: Request-URL too Large" error. Is there a way to <strong>POST</strong> the parameters to the external URL? Maybe using a different tag / tag library?</p>
