因此,当我访问主域 www 上不存在的页面时,我只会出现正常的 404 错误,但是当我在子域(如 dsfds.test.com)上访问该页面时,我会收到错误 500,并且在日志中出现以下内容:
[Thu Feb 06 15:46:41.935207 2020] [core:error] [pid 4744] [client 162.158.154.254:32186] AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.
这是我的.htaccess:

我的 VPS 上有许多不同的网站,并有许多子域名重定向。
这是网络错误:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at webmaster@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

非常感谢您的帮助。

是的,这里的每个来自子域的 URI 都有一个重写循环,这些 URI 不映射到文件名或目录。
例如,如果客户带着mail.indst.eu/nofile
- 命中子域规则 mail.indst.eu 的条件 !^/mail -> 重写为 mail.indst.eu/mail/nofile
- 不再匹配 !^/mail,不符合任何外部重定向规则,因此最后失败。
- 与现有文件的重写排除或某个硬编码排除不匹配
- 命中非主机绑定的 all-uri 规则,重写为 mail.indst.eu/index.php
- 现在它再次匹配子域规则 mail.indst.eu 的条件 !^/mail -> 重写为 mail.indst.eu/mail/index.php
- 不再匹配 !^/mail,不符合任何外部重定向规则,因此最后失败。
- 命中非主机绑定的 all-uri 规则,显然 mail/index.php 不是现有文件,因此 /mail/index.php 被重写为 /index.php,现在我们在 /index.php 和 /mail/index.php 之间交替重复
/nofile
/mail/nofile (does not exist)
/index.php
/mail/index.php (does not exist)
/index.php
/mail/index.php (does not exist)
...repeat last two...
如果您将 index.php 放在子域使用的子目录中,则子域中不存在的文件 uri 将最终出现在匹配的 subdomain/index.php 文件中,这对于某些应用程序来说可能是您想要的。如果您想要服务器级 404 响应,那么您必须将子域主机从对 index.php 的 catchall 重写中排除。
例如
RewriteCond %{HTTP_HOST} !^mail\.indst\.eu$
RewriteCond %{HTTP_HOST} !^www\.statesanalytics\.com$
RewriteRule ^.*$ index.php [NC,L]
或者,这可能更简洁,并允许更多子域名:
RewriteCond %{REQUEST_URI} !^/mail
RewriteCond %{REQUEST_URI} !^/sa
RewriteRule ^.*$ index.php [NC,L]
如果 mail.indst.eu/starting-path 中不存在 uri,则该 uri 在服务器级别上不存在,如果它在 mail/starting-path 中不存在
还有其他技术可以防止此类循环。如果你知道最多只有一个内部重定向例如,所有重写规则都位于这一个 .htaccess 中,那么您可以这样做第一的.htaccess 中的重写规则:
RewriteCond %{ENV:REDIRECT_STATUS} !^$
RewriteRule ^(.*)$ - [L]
这会阻止来自此 .htaccess 的进一步内部重定向。但这需要您将外部重定向规则放在内部重定向规则之前。它不会阻止 RedirectMatch 规则。
或者,如果你知道对 index.php 的全面重写应该总是最后一个字用 [END] 结束 mod_rewrite 处理。但在这种情况下,这意味着子域名上的 404 最终会进入主目录 index.php,这可能不是您想要的。
RewriteRule ^.*$ index.php [END]
