如何禁用 Ajax 缓存? [英] How to disable Ajax caching?

问题描述

我遇到了 ajax 缓存问题，这也是 IE 浏览器中的问题，但我通过编写以下代码修复了它.

I am having an issue with ajax caching, This was a problem in IE browser too but i fixed it by Writing the Following code.

    response.setHeader("Cache-Control", "no-cache");
    response.setHeader("expires","-1");
    response.setHeader("pragma","no-cache");

但我看到 MAC 上的 Safari4.0 正在缓存 Ajax 请求(我们需要支持这一点).火狐从来都不是问题.关于这个过期"，我将它设置为 -1，我看到很多地方将它设置为 0 或过去的某个旧日期.会有所作为吗?

But I see Safari4.0 on MAC is Caching the Ajax request(We have a requirment to support this). Fire Fox never a problem. Regarding this "Expire" i am setting it to -1, i see lot of places it is set 0 or some old date from past. Will it make a difference?

推荐答案

在您的 GET 请求中发送一个永远不会相同的额外参数，例如，当前时间戳.类似的东西:

Send an extra parameter with your GET request that will never be the same, for example, the current timestamp. Something like:

url = url + '&nocache=' + new Date().getTime();

这将阻止缓存.
