title: JSP : Hidden field is not getting submitted
body: <p>I am using following code in JSP file,but I see that the value of hidden field is not getting submitted</p>
  
  <pre><code>&lt;form action="/processor/RequestActivityByCsv" method="post" enctype="multipart/form-data"&gt;
  &lt;div class="inputDiv"&gt;
     &lt;h5&gt;comma delimited file: &lt;input type="file" name="file"/&gt;&lt;/h5&gt;
     &lt;input name="csrfToken" type="hidden" value="&lt;%=CryptoUtils.generateCsrfToken()%&gt;" /&gt;
     &lt;input type="submit" value="upload" class="btn btn-primary"/&gt;
  &lt;/div&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>in the page source this comes as :</p>
  
  <pre><code>&lt;form action="/processor/RequestActivityByCsv" method="post" enctype="multipart/form-data"&gt;
        &lt;div class="inputDiv"&gt;
           &lt;h5&gt;comma delimited file: &lt;input type="file" name="file"/&gt;&lt;/h5&gt;
           &lt;input name="csrfToken" type="hidden" value="t5ipRVFNIP83IUh5NCf7PiTp4mM2kBFVdHjqwlGx7PI=" /&gt;
           &lt;input type="submit" value="upload" class="btn btn-primary"/&gt;
        &lt;/div&gt;
   &lt;/form&gt;
  </code></pre>
