我创建了一个网站，我选择使用 .htaccess 文件而不是 appcache 或其他文件。问题是，当我更改文件时，更改不会显示（我相信这是由于 .htaccess 文件造成的）
这是我的.htaccess 文件：
<IfModule mod_headers.c>
Header unset ETag
</IfModule>
FileETag None
<IfModule mod_expires.c>

ExpiresDefault "access plus 1 month"

答案1
您设置一周、一个月、一年的缓存……它的作用正如您所期望的：浏览器会在指定的时间内缓存文件的旧版本。
从日志中可以看出，您的浏览器甚至无法访问这些文件。您可以使用 Ctrl+F5 强制重新加载或缩短缓存时间。当然，您的过期时间更改只会在第一次过期或强制重新加载后生效。
