Given the situation where your application has no special treatment from the server, you will have to just keep trying until the server gives you the page. 考虑到您的应用程序没有服务器特殊处理的情况，您将不得不继续尝试直到服务器为您提供页面。
Keep in mind that this may be a very bad idea during actual server outages (not just high-load) so you may want to report failure to the user and tell them to try again later. 请记住，在实际服务器中断（不仅仅是高负载）期间，这可能是一个非常糟糕的主意，因此您可能希望向用户报告故障，并告诉他们稍后重试。
