某些浏览器缓存验证码,导致重新打开该页面时总提示验证码过期。
刷新浏览器就正常。

你在验证码图片生成程序中加入禁止缓存的头

header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");    // Date in the past<br />header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");<br />header ("Cache-Control: no-cache, must-revalidate");  // HTTP/1.1<br />header ("Pragma: no-cache");                          // HTTP/1.0<br />
Copy after login
就可一劳永逸的解决这个问题,而不必每到使用时去改变url
