这是什么这个HTTP授权重写规则呢？ [英] What does this this HTTP Authorization RewriteRule do?

问题描述

我有一个重写递归错误的地方在我的网站，谷歌博特造成的，但我无法找出导致它，因为我的日志级别较低的URL。我提出，但一直没有再次到目前为止发生了。

I have an rewrite recursion error somewhere on my website that Google Bot caused, but I can't find the url that caused it because my Loglevel is low. I raised it but it has not happened again so far.

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

所有的RewriteRules看起来很好对我有[L]标志，除了这一个。

All Rewriterules look fine to me and have the [L] flag, except this one.

我不是很明白。它是来自开源网店系统Magento的。

I can't quite understand it. It is from the open source shop system Magento.

据我可以告诉它什么也不做，但设置环境变量E.但是是不是这样做的一个非常愚蠢的办法吗？你不应该使用setenv如果是这样的目标呢？

As far as I can tell it does nothing but sets the environment variable E. But isn't that a very stupid way of doing that? Shouldn't you use SetEnv if that was the goal?

推荐答案

这行设置环境变量，用户认证字符串的值 - 基本设置一个变量，而不是恒定值。据我所知，SETENV和SetEnvIf之后只允许设置一个环境变量设置为predetermined不变。

This line is setting the environment variable to the value of user authentication string - essentially setting a variable rather than constant value. As far as I know, SetEnv and SetEnvIf only allow you to set an environment variable to a predetermined constant.

该变量被设置实际上是HTTP_AUTHORIZATION，不E.我猜想，这是用户的认证过程的一部分。

The variable being set is actually HTTP_AUTHORIZATION, not E. I would guess this is part of the user authentication process.
