java - 防止用户在浏览器的多个选项卡/窗口中打开 JSF 页面

Question

是否可以阻止用户在多个浏览器选项卡或窗口中打开 JSF 页面？

Answer 1

我同意接受的解决方案，但如果你仍然必须这样做，这些步骤对我有用(伪代码/伪python):

在 JS 方面:

if tabId not set:
  . generate random number 
  . set property in sessionStorage
otherwise:
  . get it from sessionStorage
make an ajax callback and send tabId
onError:
  . alert(); 
  . close current tab (if possible);
  . logout

后端:(JSF):

Create custom filter:
  if request contains the tabId info:
    if it matches session's tabId: (being tabId not null)
      sent response status code to an error such as forbidden
      Optionally invalidate session
  otherwise apply session filtering (do nothing)
