Posted by: fat32 Posted on: 2003-10-24 14:21 我的程序通过HttpServetResponse OutputStream将一个图片写到页面我通过 response.setHeader("Pragma", "No-cache"); response.setDateHeader("Expires", 0); response.setHeader("Cache-Control", "no-cache"); 来设置禁止浏览器cache，但好像并不能其作用，哪位DX知道怎么回事啊？

Posted by: floater Posted on: 2003-10-25 03:20 check which version of HTTP your server is using. try no-store for Cache-Control. You may search w3c HTTP spec. Which browser are you using? Not sure whether they honor these(they should do this, but it's not that must do this).
