CakePHP在响应头中发送多行相同的cookie信息。为什么？

Question

我遇到了一个CakePHP应用程序的问题。我的应用程序在页面上显示一个大的html表格。我注意到，当表超出一定的大小限制时，IE无法显示该页面。在试图弄清楚为什么发生这种情况时，我注意到我的html响应头包含大量重复相同内容的行。

请注意响应标题中'Set-Cookie'的巨大重复行集。这只发生在我尝试显示大型表格时。有没有人有任何线索可能造成这种情况？任何帮助找到问题表示赞赏。

我正在使用CakePHP 1.2.5。据我所知，我不会搞乱任何设置的cookie功能。但是，我正在使用会话变量。

你使用的是requestAction()？然后https://dev.cakephp.org/ticket/2886可能会描述你的问题。

我有一个类似的问题，其中Set-Cookie标题重复了三次，显然是因为会话是由SessionComponent和SessionHelper两者启动的。我通过在config/core.php中设置Session.start到false然后在AppController->beforeFilter()中手动调用$this->Session->activate()来解决这个问题。
