我在使用浏览器缓存时遇到问题。我已经创建了这个 .htaccess 文件并在我的服务器上使用它,但它似乎不起作用,我从这里复制了这个“ http://www.samaxes.com/2011/05/improving-web-performance-with- apache 和 htaccess/ "。我很可能犯了一个基本错误,所以任何帮助都会很好。这里有一些细节。我正在开发一个子域,我们将其称为“子”,将主域称为“示例”。所以我希望http://sub.example.com/中的所有内容都可以处理 htaccess 文件。例如,在我的服务器上,我将 .htaccess 文件放在子目录的主目录中,该目录与主目录分开。
我正在运行一个同时启用了 mod_headers 和 mod_expires 的 apache2 服务器。
干杯。
