php - 什么是重定向 ://in PATH_TRANSLATED?

Question

我有一个 .htaccess 规则，将对 /category/category-slug/ 的请求传递给 category.php。但是，当我检查 $_SERVER 超全局时，我得到了这个条目:

Array
(
    [PATH_TRANSLATED] => redirect://
)

那是什么？我以前从未见过 redirect://。

这是相关的 .htaccess 规则:

RewriteRule ^category/([^/]+)/?(.*) /category.php?cat=$1&page=$2 [L,QSA]

因此，我的脚本中似乎没有填充 $_GET['cat'] 或 $_GET['page']来自重定向并且没有简单地重写请求。怎么回事？

我找到了一个 Apache bug report (40781)关于什么似乎是同一个问题。引用comment by Bob Ionescu :

"The problem is that the subrequest with uri=path_info of the main request (in order to obtain path_translated, i.e. the physical path view of path_info) hits the RewriteRule in per-directory context again and matches; hence no physical path.

Why does this not occur in Apache 2.0? The answer is simple: mod_rewrite doesn't act in subrequests in per-directory context prior version 2.1. The NS flag prevents the processing of RewriteRules in subrequests."

评论表明您应该能够通过包含 [NS] flag 来解决此问题在您的 RewriteRule 中，除非您明确希望它们也适用于子请求。
