如何强制Firefox不缓存响应?我们试过了:

response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
response.setHeader("Pragma", "no-cache"); // HTTP 1.0.
response.setDateHeader("Expires", 0); // Proxies.

但在约:缓存中我们仍然看到:

Firefox将始终(除非空间不足)将数据存储在其缓存中,这样它就可以通过从缓存中提取数据来执行查看源,另存为等操作。当然,如果数据设置为“no-cache”,它可能不会将它用于正常的页面加载。

如果数据是no-store,它会根据请求将缓存条目放入内存而不是磁盘。
