HTML5 AppCache：有人可以解释清单文件中 NETWORK 部分的用途吗？
HTML5 AppCache: Can somebody explain purpose of NETWORK section in manifest file?
我已经阅读了 html5rocks，mozilla 开发者文档。这些定义非常混乱。谁能用简单的术语解释一下？
我不确定为什么我们甚至需要应用缓存清单文件中的 NETWORK 部分。我认为这和在 CACHE 部分没有条目一样好。
网络Mozilla:
Files listed under the NETWORK: section header in the cache manifest
file are white-listed resources that require a connection to the
server. All requests to such resources bypass the cache, even if the
user is offline. The wildcard character * can be used once. Most sites
need *.
网络HTML5Rocks:
Files listed in this section may come from the network if they aren't
in the cache, otherwise the network isn't used, even if the user is
online. You can white-list specific URLs here, or simply "", which
allows all URLs. Most sites need "".
NETWORK: 是需要 用户在线的资源。

NETWORK:
Files listed in this section may come from the network if they aren't in the cache, otherwise the network isn't used, even if the user is online. You can white-list specific URLs here, or simply "*", which allows all URLs. Most sites need "*".
一般做法是使用 CACHE 部分定义应缓存哪些资源，然后使用带有 * 通配符的 NETWORK 部分来默认所有其他资源以要求用户在线。
示例：
CACHE:
# These resources will be downloaded once to be cached on the client.
# After they are cached, even if the user has a network connection,
# they will not re-download these resources, but instead use their local
# cached copies instead.
/favicon.ico
/index.html
/images/banner.html
# This section will explicitly tell the client "every other resource"
# requires a network connection.
NETWORK:
*
那么，为什么要明确告诉客户端所有其他资源都需要网络连接？

If you cache index.html but not cat.jpg, that image will not display on index.html even if you’re online.
