Caching is enabled by default in Chromium engine. The persistent cache data is stored in the Cache folder of the Chromium's data directory. For example, c:\Users\<username>\AppData\Local\JxBrowser\jxbrowser-chromium-43.0.2357.52.6.2\data\Cache\(默认情况下，Chromium引擎中启用了缓存。永久性缓存数据存储在Chromium数据目录的Cache文件夹中。例如，c：\ Users \ <用户名> \ AppData \ Local \ JxBrowser \ jxbrowser-chromium-43.0.2357.52.6.2 \ data \ Cache \)

Chromium API doesn't provide functionality that allows disabling cache at all, but it provides functionality that allows clearing cache storage. The following example demonstrates how to clear persistent cache storage using JxBrowser Cache API:(Chromium API不提供禁用缓存的功能，但提供了清除缓存存储的功能。以下示例演示了如何使用JxBrowser缓存API清除持久性缓存存储：)

import com.teamdev.jxbrowser.chromium.Browser;
import com.teamdev.jxbrowser.chromium.BrowserContext;

/**
 * This sample demonstrates how to clear the Browser's cache. If you create
 * several browser instances by calling new Browser() or
 * new Browser(BrowserContext context) method using the same
 * BrowserContext instance, calling CacheStorage.clearCache()
 * will remove cache for all these browser instances.

public class ClearCacheSample {
    public static void main(String[] args) {
        BrowserContext context1 = new BrowserContext("C:\\my-data1");
        Browser browser1 = new Browser(context1);
        Browser browser2 = new Browser(context1);

        BrowserContext context2 = new BrowserContext("C:\\my-data2");
        Browser browser3 = new Browser(context2);

        // Clears cache of browser1 and browser2 instances because they use the same
        // user data and cache "C:\\my-data1" directory. It doesn't clear cache
        // of browser3, because browser3 uses a different directory for storing
        // cache data - "C:\\my-data2".
        browser1.getCacheStorage().clearCache();
    }
}
