title: Getting 403 error when using CSRF filter with tomcat 6.0.32
body: <p>This is my filer config in web.xml</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;filter&gt;
      &lt;filter-name&gt;CSRFPreventionFilter&lt;/filter-name&gt;
      &lt;filter-class&gt;org.apache.catalina.filters.CsrfPreventionFilter&lt;/filter-class&gt;
      &lt;init-param&gt;
          &lt;param-name&gt;entryPoints&lt;/param-name&gt;
          &lt;param-value&gt;/login&lt;param-value&gt;
      &lt;/init-param&gt;
  &lt;/filter&gt;
  
  &lt;filter-mapping&gt;
      &lt;filter-name&gt;CSRFPreventionFilter&lt;/filter-name&gt;
      &lt;url-pattern&gt;/*&lt;/url-pattern&gt;
  &lt;/filter-mapping&gt;
  &lt;filter&gt;
  </code></pre>
  
  <p>Am I missing something? Are any code-changes necessary to enable csrf protection in tomcat</p>
