Question

我试图限制PDF文件的缓存,

response.setHeader("Cache-Control", "no-store");
response.setHeader("Expires", "0");

这对IE 8. 有效,但它在IE 9 方面有缺陷,它仍在将文件存于Temoporary Internet文件文件夹中。

谁能把灯亮一下吗?

感谢 & amp; 注意,

Answer 1

response.setDateHeader("Expires", 1L);
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.addHeader("Cache-Control", "no-store");

我通常都用这个

Answer 2

我用过这个,效果也不错

// Set to expire far in the past.
response.setHeader("Expires", "Mon, 23 Aug 1982 12:00:00 GMT");

// Set standard HTTP/1.1 no-cache headers.
response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate");

// Set IE extended HTTP/1.1 no-cache headers (use addHeader).
response.addHeader("Cache-Control", "post-check=0, pre-check=0");

// Set standard HTTP/1.0 no-cache header.
response.setHeader("Pragma", "no-cache");

Answer 3

只要这样,我就可以在Ie9
上工作

response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate");<br/>
response.setHeader("Pragma","no-cache");<br/><br/>

但如果我加上

response.addHeader("Cache-Control", "post-check=0, pre-check=0");<br/>

then it does NOT work...

Answer 4

Cache-Control: no-cache, must-revalidate
Expires:Sat, 26 Jul 1997 05:00:00 GMT

应该是你想要的

Answer 5

我没有IE9,但您不妨在Cache- control 上进一步探讨。
