javascript - State of Ajax request on response.getWriter().write() -

i have spring mvc webapp, have following controller

@resourcemapping("getpermission")     @responsebody     public modelandview getpermission(resourcerequest request,             resourceresponse response){ . .do something.. .                 iterator<string> iterator = permissionlist.iterator();                                   while(iterator.hasnext()){                         string perm = iterator.next();                         if(perm.equalsignorecase("create")){                             response.getwriter().write("true");                         }                     }                 return null; } 

and ajax request

$.ajax({    url:availableurls.permurl,    success:function(result){     if(result=='true'){        something..          }   } }); 

now when response.getwriter().write("true"); ajax request closed? or if permissionlist has got more 2 values create, write true twice?

will request closed once write response or not confusion. support appreciated.
