Htaccess - 如果未设置env var,则跳过重定向

Question

当一个特定的env变量没有被前一个"RewriteRule"设置时,我只想跳过用"RewriteRule"完成的重定向.

这是我的例子,它不起作用.

RewriteEngine on
RewriteBase /

#
# if /internal ... set ENV var INTERNALAREA = true
#
RewriteRule ^internal(.*)$ - [E=INTERNALAREA:true]

#
# Redirect to /maintenance.php if not in internal area and not already at /maintenance.php
#
RewriteCond %{ENV:INTERNALAREA} !true
RewriteCond %{REQUEST_URI} !^/maintenance.php$
RewriteRule ^(.*)$ /maintenance.php [R=302,L]

#
# Default TYPO3 rewrites
#
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)\.(\d+)\.(php|js|css|png|jpg|gif|gzip)$ $1.$3 [L]

RewriteRule ^fileadmin/(.*/)?_recycler_/ - [F]
RewriteRule ^fileadmin/templates/.*(\.txt|\.ts)$ - [F]
RewriteRule ^typo3conf/ext/[^/]+/Resources/Private/ - [F]
RewriteRule ^(typo3/|t3lib/|fileadmin/|typo3conf/|typo3temp/|uploads/|favicon\.ico) - [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule .* index.php [L]

在维护PHP我有一个phpinfo()输出$_SERVER['REDIRECT_REDIRECT_INTERNALAREA'] = true.

我总是被重定向到maintenance.php访问时/internal/....

我究竟做错了什么？

Answer 1

我找到了问题的答案.问题源于以下问题:

在Apache RewriteRule指令中设置环境变量时,是什么导致变量名称以"REDIRECT_"作为前缀？

现在,在所有其他规则之前设置以下内容时,一切都按预期工作:

RewriteCond %{ENV:REDIRECT_INTERNALAREA} (.+)
RewriteRule .* - [E=INTERNALAREA:%1]

下面是它的工作原理.如果已经设置了带前缀的env var,它会检查每次运行,并重新添加没有REDIRECT_前缀的环境变量.
