在Google App Engine中_ah意味着什么？ [英] What does _ah mean in Google App Engine?

问题描述

_ah 是否代表Google App Engine中的任何内容？

我并不想知道它用于或位于何处以及它如何工作。正如下面提到的一些答案，这是管理员的保留路径。

但是， a 和 h 这两个字母是否是缩写或其他？

解决方案

它来自apphosting，下划线是让它更难与用户提供的某个URL相冲突。

编辑：我在谷歌工作，apphosting是他们为AppEngine选择的第一个名字，这个名字仍然存在于内部配置的某些部分。

Does the _ah mean anything in Google App Engine?

I'm not looking to find out what it's used for or where is it located and how it works. As some answers below mentioned it's a reserved path for admin stuff.

But the letters, a and h together, is it an abbreviation or something?

解决方案

It comes from apphosting, the underscore is to make it more difficult to collide with some user provided URL.

Edit: I worked at Google, apphosting was the first name they selected for AppEngine, and this name still remains in some parts of the internal configuration.
