问题描述

例如
＆LT;脚本类型=文/ JavaScript的SRC =资产/脚本/ somescript.php＆GT;＆LT; / SCRIPT＆GT;
将我的浏览器仍然只是通过不设置此脚本缓存这个报头meta标签缓存，必重新验证？

for example <script type="text/javascript" src="assets/scripts/somescript.php"></script> will my browser still cache this just by not setting this scripts headers meta tag cache to must-revalidate?

推荐答案

有些浏览器更具有侵略性比其他默认的缓存。不过，也有您可以发送指示何时重新加载$ ​​C $ C缓存控制头。

Some browsers are more agressive with default caching than others. However, there are cache control headers you can send to indicate when to reload the code.

header("Expires: " . date("r", time() + ( 60 * 60 * 24 * 7 * 1 ) ) ); // Expires in 1 week
header("Content-Type: application/x-javascript");

是一个code-片段我已经知道使用。

您可以使用更花哨的东西，如若非-Modified头和ETag，而到期时间是消除额外的服务器调用唯一的。

You can use more fancy stuff like If-Not-Modified headers and ETags, but Expire times are the only ones that eliminate extra server calls.
