推荐答案

刷新页面时，您以前执行过POST操作而不是GET.

提示您必须重新执行POST才能刷新页面，需要再次将数据发送到服务器以检索结果.

这是设计使然和预期的行为. Y

When you''re refreshing the page, you have previously performed a POST operation rather than a GET.

You are being told that you cannot refresh the page without performing the POST again, you need to send the data to the server again to retrieve the results.

It''s by design and expected behaviour. Y

如果编写避免缓存的代码，浏览器将强制刷新

如果您在page_load方法中添加以下代码，则可以避免页面被缓存

Browser forces refresh if you write the code for avoiding caching

if you add below code in your page_load method, it avoids cahing of the page

Response.Cache.SetCacheability(HttpCacheability.NoCache);
       Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
       Response.Cache.SetNoStore();

当您单击刷新按钮时，浏览器将查找缓存的页面，但是如果您有意避免缓存，则它将从服务器获取副本.

如果您使用NoCache逻辑，则删除该代码可能会对您有所帮助.

when you hit refresh button browser looks for cached page, but if you intentionally avoid caching, then it will take the copy from server.

if you used NoCache logic, removing that code may help you.
