body: <p>I am using tomcat 8.52 to fix CSRF issue. In that 
   am using org.apache.catalina.filters.CsrfPreventionFilter. </p>
  
  <ol>
  <li><p>How can I use entryPoints param with regex pattern matching.</p></li>
  <li><p>How I can avoid CSRF checking in my login page. </p></li>
  </ol>
  
  <p>My login page loads 20 js,40 imags,23 css. How all are can I mention in the entrypoint param?</p>
  
  <p>My web.xml:</p>
  
  <pre><code>    &lt;filter&gt;
      &lt;filter-name&gt;CsrfFilter&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;denyStatus&lt;/param-name&gt;
        &lt;param-value&gt;404&lt;/param-value&gt;
      &lt;/init-param&gt;
    &lt;init-param&gt;
    &lt;param-name&gt;entryPoints&lt;/param-name&gt;
      &lt;param-value&gt;/mUser/login,/js/encrypt.js,/js/json-min.js,/m    User/homepage,/dispatch/sendtemplate&lt;/param-value&gt;
    &lt;/init-param&gt;
  </code></pre>
  
  <p>When I try to login with my pages, I am seeing only encrypt.js,json-min.js only loaded others are showing 404 error.
  Also getting 404 page while logging to the page.</p>
