title: Spring Security Performances
body: <p>My web app is using Spring Security 3 as login manager and users data (username, password, etc) are saved on database.
  Now we added external applications that are supposed to use the same login page internally to the first app. That could be a problem especially for performance reasons. Is it possible take out the "spring security part" as a separate module? How can I keep in this case the redirection working in the main application? Design suggestions?</p>
