警告，页面已过期，这个大家是怎么解决的？
页面的结果是搜索出来的，删除某条信息返回后就出现警告说页面已过期

有人说在session_start();后面加上
header("Cache-control: private");

加了之后是没有警告了，但是又有另外一个问题了

就是点击删除后，页面还是一样的，要再按搜索，才出现删除完那条信息的结果，怎么会这样的呢？这又怎么解决啊~~

------解决方案--------------------
删除后，显示的页面你没有传关键字给它啊
------解决方案--------------------
加一个随机数在url参数里吧。
------解决方案--------------------
他是表单提交后 js // history.back(-1) 的问题
改成用 location.href='prevpage.php' 或php代码 @header('location:prevpage.php');
------解决方案--------------------

探讨

但是刷新了，之前搜索的条件不就没了吗？引用:
点击删除了刷新页面没有呢
