內容簡介
FlexiCache是一個快速、功能齊全且靈活的快取系統，可改善任何WordPress網站的性能和可用性。
它高度可配置，可以允許無限的快取規則-在不同的時間過期不同的頁面，不快取某些頁面，根據瀏覽器、語言等快取同一頁面的多個版本。
FlexiCache也可以直接開箱即用，不需要進行複雜的配置。
功能
使用用戶定義條件進行廣泛的配置
處理高流量期間，當多個客戶端可能同時請求未快取或過期的項目
獨立模式，繞過WordPress和第三方主題和插件代碼來更快地提供快取頁面
存儲引擎的選擇：文件系統，Memcache和SQLite
預快取功能，可以在現有頁面過期之前緩存新版本的頁面
使用Filesystem和Memcache存儲庫的SQLite索引，可以加速從快取中刪除特定項目的速度（如果有可用的SQLite，則自動啟用）
向請求客戶端發送適當的HTTP快取標頭
以請求客戶端接受的壓縮格式提供文件
與WordPress MU兼容
升級FlexiCache
FlexiCache在插件目錄中存儲配置和快取數據（查看版本1.2.4.2+的插件文檔以了解原因）。
如果您使用WordPress的內置升級程序升級插件，則整個插件目錄將被替換，包括您的配置和快取數據。
為了保留這些數據，在升級之前複製“plugins / FlexiCache / _data”目錄，然後在升級完成後將其複製回去。
如果您直接通過SVN進行升級，則不需要這樣做，因為只會更新版本控制下的文件。
停用FlexiCache
FlexiCache可以像其他插件一樣通過管理介面停用，但如果您正在運行獨立模式，則應在停用插件之前刪除.htaccess的修改。
對於標準的WordPress安裝，可以通過管理介面進行此修改，但如果使用WordPress MU，其中多個站點可能共享相同的.htaccess文件，建議手動進行此更改。

原文外掛簡介
FlexiCache is a fast, full-featured and flexible caching system which will improve the performance and availability of any WordPress site.
It is highly configurable to allow unlimited caching rules – expiring different pages at different times, not caching some pages at all, caching multiple versions of the same page depending on browser, language, and so on.
FlexiCache will also work straight out of the box without any need for complex configuration.
Features
Extensively configurable using user-defined conditions
Handling of high-traffic periods where multiple clients may simultaneously request uncached or expired items
Standalone mode which bypasses WordPress and third-party theme and plugin code to serve cached pages faster
Choice of storage engines: Filesystem, Memcache and SQLite
Pre-caching functionality to cache new versions of pages before the existing ones expire
SQLite indexing of Filesystem and Memcache stores to speed up removing specific items from the cache (automatically enabled if SQLite is available)
Sends appropriate HTTP cache headers to the requesting client
Serves files in compressed formats accepted by the requesting client
Compatible with WordPress MU
Upgrading FlexiCache
FlexiCache stores config and cache data within the plugin directory (see plugin documentation in versions 1.2.4.2 onwards for the reason why).
If you upgrade the plugin using WordPress’s built-in upgrade process, the entire plugin directory will be replaced, including your config and cache data.
To preserve these, take a copy of the “plugins/FlexiCache/_data” directory before upgrading, and then copy it back after the upgrade is complete.
If you upgrade directly via SVN, this should not be required, since only the files under version control will be updated.
Deactivating FlexiCache
FlexiCache can be disabled via the admin interface as with any plugin, however if you are running in Standalone mode, you should remove the .htaccess modifications before deactivating the plugin.
For a standard WordPress install, this modification can be done via the admin interface, however it is recommended that you make this change manually, especially if using WordPress MU, where multiple sites may share the same .htaccess file.
Please see the documentation supplied with the plugin (accessible via WordPress’s admin interface) for more information.
