OGX-3　｜　妳木有小雞雞

从开源中国看到一则“新闻”，说：“HAproxy 1.4 正式版发布，Web负载均衡”,其内容短小的让人惊奇。进官方网站看了他的文档，觉得还挺有趣的。

动态负载均衡，支持热备配置。不过让我好奇的还是他的The HTTP transaction model，原文如下：

When haproxy is running in HTTP mode, both the request and the response are
fully analyzed and indexed, thus it becomes possible to build matching criteria
on almost anything found in the contents.

However, it is important to understand how HTTP requests and responses are
formed, and how HAProxy decomposes them. It will then become easier to write
correct rules and to debug existing configurations.

因为还从来没碰到过这样的环境，所以现在这里记录。等需要的时候仔细再研究。
