Page has Expired (php)

呼~不停的問題啊

最近發現 之前寫的網頁有問題嚕~

網頁裡面的表單送出後，再按"上一頁"
就會出現
"Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you.

To resubmit your information and view this Web page, click the Refresh button. "

目前看到的解決方法~


所以囉~到php.ini 找找"session.cache_limiter" 把值設為"private"看看~
