我有两个相同的联系表单，但后端表单上的不同STMP信息除外。
让我感到困惑的是，当我完成这两个表单并重定向到一个表单时，即当我选择通过浏览器按钮返回时，我仍然看到表单上仍然存在所有信息。然而，在另一台服务器上，当我通过浏览器的后退按钮返回时，表单已自行刷新。
为什么行为在不同服务器上的相同表单上如此一致地不同？
修改
（还要注意表格是剥离版本，即我拿出了css，jquery的东西，页脚，导航等，以保持简短快速阅读）
我决定从一台服务器中包含该表单，当您回击时，该表单始终显示联系人的信息。我想要注意的是，这种行为非常一致，并且使用相同的浏览器。他们只是在不同的服务器上。此外，即不同的PHP版本，如果这有任何区别。它是PHP会话驱动的页面。即，浏览器不应该保留信息，对吗？
