Google Speed Leverage 浏览器缓存

发布于 2024-11-25 21:26:58 字数 971 浏览 0 评论 0原文

我从 Google 速度测试中收到此错误：

以下可缓存资源的新鲜度寿命很短。为以下资源指定至少未来一周的到期时间：

http://localhost/english/favicon.ico (expiration not specified)
http://localhost/english/images/bg_center.png (expiration not specified)
http://localhost/english/images/bg_top.jpeg (expiration not specified)
http://localhost/english/images/footer_bg2.png (expiration not specified)
http://localhost/english/images/m_facebook.png (expiration not specified)
http://localhost/english/images/m_rss.png (expiration not specified)
http://localhost/english/images/top_bg.png (expiration not specified)
http://localhost/english/javascript/gram.js (expiration not specified)
http://localhost/english/javascript/top_start.js (expiration not specified)
http://localhost/english/jquery.js (expiration not specified)
http://localhost/english/style/gram.css (expiration not specified)
http://localhost/english/style/style.css (expiration not specified)

我应该在 htaccess 文件中执行某些操作吗？

看起来静态文件没有设置过期时间。阅读 - http://www.absolutelytech.com/2010/08/02/howto-add-expire-headers-to-cache-static-files-using-htaccess/

您需要将以下代码发布到 .htaccess 中

# Turn on the Expires engine
ExpiresActive On

# Expires after a month client accesses the file
ExpiresByType image/jpeg A2592000
ExpiresByType image/gif A2592000
ExpiresByType image/png A2592000
ExpiresByType image/x-icon A2592000
ExpiresByType text/plain A2592000

# Good for one week
ExpiresByType application/x-javascript M604800
ExpiresByType text/css M604800
ExpiresByType text/html M604800

Looks like the static files don't have expires set. Read - http://www.absolutelytech.com/2010/08/02/howto-add-expire-headers-to-cache-static-files-using-htaccess/

You'll need to post the below code in your .htaccess

# Turn on the Expires engine
ExpiresActive On

# Expires after a month client accesses the file
ExpiresByType image/jpeg A2592000
ExpiresByType image/gif A2592000
ExpiresByType image/png A2592000
ExpiresByType image/x-icon A2592000
ExpiresByType text/plain A2592000

# Good for one week
ExpiresByType application/x-javascript M604800
ExpiresByType text/css M604800
ExpiresByType text/html M604800

PageSpeed：利用浏览器缓存
每次浏览器加载网页时，它都必须下载所有网络文件才能正确显示该页面。这包括所有 HTML、CSS、javascript 和图像。

要启用浏览器缓存，您需要编辑 HTTP 标头以设置某些类型文件的到期日期。

在域的根目录中找到 .htaccess 文件，该文件是隐藏文件，但应该显示在 FileZilla 或 CORE 等 FTP 客户端中。您可以使用记事本或任何形式的基本文本编辑器编辑 htaccess 文件。

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>

PageSpeed: Leverage browser caching
Every time a browser loads a webpage it has to download all the web files to properly display the page. This includes all the HTML, CSS, javascript and images.

To enable browser caching you need to edit your HTTP headers to set expiry dates on certain types of files.

Find your .htaccess file in the root of your domain, this file is a hidden file but should show up in FTP clients like FileZilla or CORE. You can edit the htaccess file with notepad or any form of basic text editor.

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>
