重定向301仅对某些网址有效

Question

出于某种原因，我突然无法让我的Redirect 301s工作。 .htaccess文件如下。我只粘贴了第10个Redirect 301命令，但有超过100个。

301重定向都具有相同的格式，但列出的前六个没有效果。最后四个（后跟“ ** ”）按预期运行。我看不到任何解释。

有什么想法吗？

解释是您无法在Redirect或RedirectMatch语句的模式中与查询字符串进行匹配。声明：

Redirect 301 /homecare/10-caring-companion/index.php?option=com_content&view=article&id=89&Itemid=75 http://www.caringcompanion.net/concord-ma

实际上尝试匹配此URI：

/homecare/10-caring-companion/index.php%3Foption=com_content%26view=article%26id=89%26Itemid=75

而不是查询字符串（?之后的所有内容）。您需要使用mod_rewrite中的%{QUERY_STRING} var来匹配它。所以像这样：

RewriteCond %{QUERY_STRING} ^option=com_content&view=article&id=89&Itemid=75$ 
RewriteRule ^/?homecare/10-caring-companion/index\.php$ http://caringcompanion.net/concord-ma [L,R=301]

RewriteCond %{QUERY_STRING} ^option=com_content&view=article&id=94&Itemid=75$ [OR]
RewriteCond %{QUERY_STRING} ^option=com_content&view=article&id=94&Itemid=74$
RewriteRule ^/?homecare/10-caring-companion/index\.php$ http://caringcompanion.net/cambridge-ma [L,R=301]

RewriteCond %{QUERY_STRING} ^option=com_content&view=article&id=94:cambridge-ma-home-care-elderly-caregivers&catid=38:cambridge&Itemid=74$
RewriteRule ^/?index\.php$ http://caringcompanion.net/cambridge-ma [L,R=301]

RewriteCond %{QUERY_STRING} ^option=com_content&view=article&id=93:acton-ma-home-care-elderly-caregivers&catid=34:acton&Itemid=70$
RewriteRule ^/?index\.php$ http://caringcompanion.net/action-ma [L,R=301]

RewriteCond %{QUERY_STRING} ^option=com_content&view=article&id=93&Itemid=70$ 
RewriteRule ^/?homecare/10-caring-companion/index\.php$ http://caringcompanion.net/action-ma [L,R=301]

RewriteCond %{QUERY_STRING} ^option=com_content&view=article&id=52&Itemid=158$
RewriteRule ^/?homecare-ma/ma/index.php$ http://caringcompanion.net/homecare-massachuetts-maine-new-hampshire [L,R=301]

根据您拥有的其他Redirect，您可能会发现自己被重定向到未明确制作的意外网址。重写规则（mod_rewrite）和重定向（mod_alias）可能相互干扰，因为这两个模块应用于URL文件映射引擎的不同点，并且两个模块最终可能会破坏相同的URI。如果发生这种情况，你应该坚持只使用mod_rewrite进行重定向，因为你需要重写引擎来匹配查询字符串。
