我的代码在过去 2 年一直在生产环境中没有问题，上周我们的托管公司关闭了两天，当服务器重新上线时，我们的应用程序开始出现特定问题。

这个问题是当您尝试登录时，它会将您带回到登录页面而没有错误。我提交了一张 troble 票，并被要求清除我的浏览器缓存。我清除了缓存，应用程序又开始工作了。

如果不清除浏览器缓存，是否没有其他方法可以解决此问题？

我尝试了几种方法，我用过

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />

并且还使用了

<cflocation url="index.cfm" addtoken="yes">

请参阅 Application.cfc 的代码

<cfcomponent>

如果您使用这些命令，您可以清除服务器上的应用程序变量，如果您想重置任何变量并重新启动应用程序，您也可以使用 structClear()。一般来说，一旦设置了应用程序变量，它们就会在内存中持久存在，直到应用程序重新启动。

这些命令将重新启动应用程序。

<cfscript> applicationStop(); </cfscript> or <cfset applicationStop()>

清除变量后，您可以删除该行代码，这应该可以解决缓存问题。
