title: HTTP 302 moved temporarily on spring security login with Grails
body: <p>I am using Grails with Spring Security without any customization. </p>
  
  <p>The problem occurs only in production environment: 
  When entering login information, I am redirected to the login screen with the HTTP code <code>302 moved temporarily</code>, but only the in the first try. All other attempts will be well succedded.</p>
  
  <p>I tested several times using incognito tab, and absolutely always this happens.</p>
  
  <p>I´m using Apache Tomcat 7, Grails 2.3.4 and Spring Security 2.0 RC2, totally default.</p>
