java - Spring MVC HandlerInterceptor : Redirect Failed -

i have created simple webmvc application - handler interceptor configured. interceptors responsibility simple - should check if valid session exists in httprequest - , if true, redirect registration page.

the issue encounter on redirect - browser throwing message:

the page isn't redirecting properly

firefox has detected server redirecting request address in way never complete.

the interceptors code follows:

public class logininterceptor extends handlerinterceptoradapter{    // used checking session management user. @override public boolean prehandle(httpservletrequest request,                          httpservletresponse response,                          object handler) throws exception {       system.out.println(" <interceptor> - pre handle");      return true; }   @override public void posthandle(httpservletrequest request,                        httpservletresponse response, object handler,                        modelandview modelandview) throws exception {      system.out.println(" <interceptor> - post handle");      httpsession session = request.getsession();     user user = (user) session.getattribute("user");       system.out.println(" <interceptor> - session id --> " + session.getid());     system.out.println(" <interceptor> - session create time --> " + session.getcreationtime());     system.out.println(" <interceptor> - session last accessed time --> " + session.getlastaccessedtime());      try {         system.out.println(" <interceptor> - user info --> " + user.tostring());     }catch(exception e){         e.tostring();     }      try{         if(session != null){             response.sendredirect("register");             return;         }     }catch(exception e){         e.tostring();     }  }   public void aftercompletetion(){     system.out.println(" <interceptor> - after completion");  } 

}

i have attempted append full request context path redirect - root context - both of fail. cannot see failing on - appreciated.

whatever interceptor have written come picture requests.

so when redirect /register time reach interceptor find session not null , again redirect..and same thing continues...infinite redirection same request.

@override public void posthandle(httpservletrequest request,                        httpservletresponse response, object handler,                        modelandview modelandview) throws exception {      httpsession session = request.getsession();      try{         if(session != null){                            //infinite              response.sendredirect("register");             return;         }     }catch(exception e){         e.tostring();     }  } 

so make sure intercept 1 request configuration or code

if((request.getrequesturi().equals(contextpath+"/someuri") && session != null){     response.sendredirect("register"); } 

then check particular request , redirect register.it wont fell in infinite loop.
