title: 413 Full HEAD error
body: <p>i have made a dynamic blog engine, where multiple authors can publish articles.</p>
  
  <p>the author goes to a page where he inputs the 'article' 'description' and 'the whole article' in three <code>&lt;textarea&gt;</code> 
  Then i store all the values in 3 variables and store it in the database via an ajax based request.</p>
  
  <p>The Problem: 
  The HttpServerRequest is too large and it gives a 413 FULL Head error, and the request doesnt get through.</p>
  
  <p>The Code:</p>
  
  <p>The HTML:</p>
  
  <pre><code>&lt;div class="container"&gt;
          &lt;h4 class="text-left"&gt;Title:&lt;/h4&gt;
          &lt;textarea id="title" rows="2" cols="" &gt;&lt;/textarea&gt;
          &lt;br /&gt;
          &lt;h4 class="text-left"&gt;Description:&lt;/h4&gt;
          &lt;textarea id="description" rows="5" cols="" &gt;&lt;/textarea&gt;
          &lt;br /&gt;
          &lt;h4 class="text-left"&gt;Article:&lt;/h4&gt;
          &lt;textarea id="article" rows="40" cols="" onkeyup="replaceWordChars(this.value)"&gt;&lt;/textarea&gt;
          &lt;br /&gt;
  
          &lt;div class="publish btn"&gt;Publish&lt;/div&gt;
          &lt;br /&gt;
          &lt;br /&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>The Script:</p>
  
  <pre><code>&lt;script&gt;
      $(function(){
          $('.publish').click(function(){
              title = $('#title').val();
              description = $('#description').val();
              article = $('#article').val();
  
              $.ajax({
                  type:       "get",
                  url:        "/articles",
                  data:       {action:'add', title:title, description:description, article:article},
                  success:    function(code)
                  {
                              alert("published"); 
                              window.location="dashboard.jsp";
                  }
  
              }).error(function(){ alert("error"); })
              .complete(function(){ alert("complete"); });
  
          });
  
      });
      &lt;/script&gt;
  </code></pre>
  
  <p>The ERROR:</p>
  
  <blockquote>
    <p>"NetworkError: 413 FULL head - http:///articles?action=add&amp;title=blah&amp;..........gs.%0A%0A&amp;userId=1"</p>
  </blockquote>
  
  <p>The Question:</p>
  
  <p>Is there an alternate way to send a big server request??
  I also read on google that we can change the size, to match huge requests?</p>
  
  <p>Answers are preferred in java, HTML, javascript (or) jQuery</p>
  
  <p><strong><em>EDIT</em></strong> I read <a href="https://stackoverflow.com/questions/18093392/can-you-set-the-size-limit-of-a-post-request-in-header?lq=1">here</a> that we can set the size limit of post request in header? How can i do it in GAE?</p>
