更正 HT访问缓存参数

Question

我一直在阅读htaccess缓存的主题，以帮助提高我网站的速度。 我根据来自不同网站来源的信息将以下内容放在一起，因为我想提高我的 cms 的速度。

有人可以告诉我这是否是使用参数的正确方法吗？

Answer 1

以下行需要从以下位置更新：

SetEnvIfNoCase Request_URI .(?:gif|jpg|png)$ no-gzip dont-vary

自

SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary

您似乎也有一些重复：

Header unset Pragma
FileETag None
Header unset ETag
<IfModule mod_headers.c>
    Header unset ETag
</IfModule>
FileETag None

此外，值得合并您的<IfModule>指令，因此mod_expires的所有指令都位于一个位置，您还应该删除重复的过期设置。 例如

<FilesMatch ".(ico|jpg|jpeg|png|gif|js|css|swf|pdf|flv|mp3)$">
  <IfModule mod_expires.c>
    ExpiresActive on
    ExpiresDefault "access plus 14 days"
    Header set Cache-Control "public"
  </IfModule>
</FilesMatch>

被覆盖

<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresDefault "access plus 86400 seconds"
    ExpiresByType image/x-icon "modification plus 1 year"
    ExpiresByType image/gif "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/jpg "access plus 1 year"
    ExpiresByType text/js "access plus 1 month"
    ExpiresByType text/javascript "access plus 1 month"

除此之外，是的。
