如何使iframe会话从父页面保持活动状态

Question

I want the iframe's session to remain alive when there is an activity on the parent page. The solution I was thinking to ping an image url of iframe's domain from the parent page whenever there is some activity on the parent page. This is an ASP.Net application hosted on IIS 7.

My question is does pinging the iframe's domain from parent page will update the iframe's session ?

Answer 1

通过在父级的主体上附加单击处理程序并对子域上的任何图像发出get请求，可以实现此目的。
