[原文]ABC's of RSS Feeds
Implementing RSS (Really Simple Syndication) can be aided by an understanding of the terms relating to RSS. Learn the ABCs of RSS....
A - AutoDiscovery（自动识别）
Auto Discovery is code that is inserted into the header of an HTML web page, which then indicates to readers that an RSS feed is available for the content.
B - Blogs（博客）
Blogs are web logs that are updated regularly, usually on a daily basis. Blogs generally contain information related to a specific topic. In some cases, blogs are used as daily diaries about people's personal lives, political views, or even as social commentaries. The truth of the matter is that blogs can be shaped into whatever the author wants them to be. While initially thought of as diaries or online journals, blogs have evolved into the latest fresh web content.
C - Cache（缓存）
Cache is a temporary storage area for frequently-accessed or recently-accessed data. Having certain data stored in a cache area speeds up the operation of the computer. Using a cache with RSS feeds will help minimize bandwidth and display an RSS feed's content quicker.
