// LOAD_DEFAULT：根据cache-control决定是否从网络上取数据。HTTP 协议头里的 Cache-Control，
// LOAD_CACHE_NORMAL：API level 17中已经废弃, 从API level 11开始作用同- - LOAD_DEFAULT模式，
// LOAD_NO_CACHE: 不使用缓存，只从网络获取数据，
// LOAD_CACHE_ELSE_NETWORK，只要本地有，无论是否过期，或者no-cache，都使用缓存中的数据。
// http协议缓存机制是指通过 HTTP 协议头里的 Cache-Control（或 Expires）和 Last-Modified（或 Etag）等字段来控制文件缓存的机制。
// Cache-Control 用于控制文件在本地缓存有效时长。最常见的，比如服务器回包：Cache-Control:max-age=600 表示文件在本地应该缓存，且有效时长是600秒（从发出请求算起）。在接下来600秒内，如果有请求这个资源，浏览器不会发出 HTTP 请求，而是直接使用本地缓存的文件。
// Last-Modified 是标识文件在服务器上的最新更新时间。下次请求时，如果文件缓存过期，浏览器通过 If-Modified-Since 字段带上这个时间，发送给服务器，由服务器比较时间戳来判断文件是否有修改。如果没有修改，服务器返回304告诉浏览器继续使用缓存；如果有修改，则返回200，同时返回最新的文件。
// Cache-Control 通常与 Last-Modified 一起使用。一个用于控制缓存有效时间，一个在缓存失效后，向服务查询是否有更新。
// Cache-Control 还有一个同功能的字段：Expires。Expires 的值一个绝对的时间点，如：Expires: Thu, 10 Nov 2015 08:45:11 GMT，表示在这个时间点之前，缓存都是有效的。
// Expires 是 HTTP1.0 标准中的字段，Cache-Control 是 HTTP1.1 标准中新加的字段，功能一样，都是控制缓存的有效时间。当这两个字段同时出现时，Cache-Control 是高优化级的。
// Etag 也是和 Last-Modified 一样，对文件进行标识的字段。不同的是，Etag 的取值是一个对文件进行标识的特征字串。
// 在向服务器查询文件是否有更新时，浏览器通过 If-None-Match 字段把特征字串发送给服务器，由服务器和文件最新特征字串进行匹配，来判断文件是否有更新。
// 没有更新回包304，有更新回包200。
// Etag 和 Last-Modified 可根据需求使用一个或两个同时使用。两个同时使用时，只要满足基中一个条件，就认为文件没有更新。
