    • Embodiments of the present invention provide techniques for tracking the lifecycles of client-side browser windows in the context of a web application. In one set of embodiments, a server component of a web application can receive a notification that an application page in a first window has been unloaded/destroyed. In response, the server component can associate the first window with an expiration time and add the first window to an "expiration" list of windows that are potentially inactive. If a request is received by the server component from the first window while the first window is in the expiration list, the server component can identify the first window as active and remove it from the list. If a request is received by the server component from a second window after the expiration time associated with the first window, the server component can identify the first window as inactive and free all resources for the first window.
    • 本发明的实施例提供了用于在web应用的上下文中跟踪客户侧浏览器窗口的生命周期的技术。 在一组实施例中,web应用的服务器组件可以接收第一窗口中的应用页面已被卸载/销毁的通知。 作为响应,服务器组件可以将第一窗口与到期时间相关联,并将第一窗口添加到潜在不活动的窗口的“到期”列表。 如果服务器组件在第一个窗口处于到期列表时从第一个窗口接收到请求,则服务器组件可以将第一个窗口标识为活动状态,并将其从列表中删除。 如果服务器组件在与第一窗口相关联的到期时间之后从第二窗口接收到请求,则服务器组件可以将第一窗口识别为非活动状态并释放第一窗口的所有资源。
