內容簡介
在擁有一個網站中，最重要的其中之一就是讓它在搜尋引擎中有良好的排名。畢竟，沒有人創建一個網站時希望它被埋在Google搜索的第20頁。
CodeDragon SmartCache是一款為WordPress網站設計的強大性能和緩存系統，同時對非技術網站所有者易於理解。採用多種“分層”能力，例如縮小、結合、頁面和瀏覽器緩存以及CDN支持，SmartCache能夠實現以下目標：
1. 減少提供網絡帶寬的資源
2. 降低提供網站內容所需的時間，提高用戶體驗
3. 關注搜索索引網站所關注的關鍵方面，如Google在排名網站時會考慮的因素
安裝SmartCache後，它將自動啟用您網站的最佳設置。如果您想進一步自定義這些設置，本介紹將引導您完成一些關鍵步驟。我們最終建立了SmartCache，以便不需要對wp-config.php、.htaccess或其他網站文件進行手動更改即可啟動並運行。
縮小檔案
在最低級別上，SmartCache將縮小JavaScript、CSS樣式表、字體和HTML內容。同時，它可以自動最小化渲染阻止檔案，並去除查詢字符串。
結合檔案
通過結合檔案，SmartCache有助於減少對服務器的文件請求數量，從而縮短加載頁面所需的時間。
頁面緩存
頁面緩存更進一步實現了GZip壓縮，準備了單獨的HTTPS緩存並提供“壓平”的HTML版本。通過GZip壓縮和靜態HTML內容，頁面提供的處理更少。
瀏覽器緩存
此時，SmartCache將為數據檔案類型提供首選到期期限的指示，因此客戶端瀏覽器可以舒適地重複使用緩存檔案，直到它們過期。

原文外掛簡介
One of the most important aspects of owning a website is having it rank well with search engines. After all, no one creates a site intending for it to be buried on page 20 of a Google search.
CodeDragon SmartCache was designed as a powerful performance and caching system for WordPress websites yet easy enough for the non-technical site owner to understand. Employing several “layered” capabilities such as minifying, combining, page and browser caching and CDN support, SmartCache is able to:
Condense served resources to improve network bandwidth
Improve user experience by reducing the time it takes to offer your site content
Focus on the key aspects that search indexing sites like Google regard when ranking the site
After installing SmartCache it will automatically activate the most optimal settings for your site. If you would like to further customize these settings, this introduction will walk you through some of the key steps. A more detailed instruction is available in our Startup Document. Ultimately, we have built SmartCache so that getting up and running does not require making manual changes to the wp-config.php, .htaccess, or other site files.
Minifying
At the lowest level, SmartCache will minify Javascript, CSS stylesheets, fonts, and HTML content. As well, it can automatically minimizes render-blocking files, and remove query strings.
Combining
By combining files, SmartCache helps to reduce the number of requests for files from the server, thus shortening the amount of time required to load a page.
Page Caching
Page caching goes further by implementing GZip Compression, preparing a separate HTTPS cache and serving a “flattened” HTML version of your site’s pages. With GZIp Compression and static HTML content pages are provided with less processing from the server.
Browser Caching
At this point SmartCache instructs your server with the preferred expiry periods for several file types, so client browsers can comfortably reuse cached files until they expire.
