.htaccess中的“多视图"选项到底是什么? [英] What exactly does the Multiviews options in .htaccess?

问题描述

我一直在努力制定访问规则，该访问规则需要重写一个添加路径的URL.

I've been struggling a lot with an access rule that needed to rewrite one piece of URL adding a path.

RewriteRule ^(configuration/.+)$ application-server/$1 [L,NC,R=301,NE]

此规则仅在我的Joomla网站上导致空白页，没有错误日志或消息. 奇怪的是，我制定的所有其他规则都运行良好:

This Rule caused just a blank page on my Joomla site with no error log or messages. The curious thing is that all other rules I had worked perfectly:

RewriteRule ^(log/.+)$ application-server/$1 [L,NC,R=301,NE]
RewriteRule ^(monitor/.+)$ application-server/$1 [L,NC,R=301,NE]

最后，我在一个论坛上发现了使用以下选项的建议:

in the end, I've found in a forum a suggestion to use the following option:

Options -Multiviews

这实际上解决了问题，但是我想知道使用此选项时是否会对其他规则产生任何副作用.

That actually solved the issue, however I wonder if there can be any side effects on other Rules when using this option.

推荐答案

这是有关Apache内容协商的.

This is about Apache content negotiation.

MultiViews搜索是服务器进行隐式文件名模式匹配的位置，然后从结果中进行选择.

A MultiViews search is where the server does an implicit filename pattern match, and choose from amongst the results.

例如，如果您在根文件夹中有一个名为configuration.php(或其他扩展名)的文件，并且在htaccess中为一个名为configuration/的虚拟文件夹设置了规则，则您的规则会出现问题因为服务器将自动选择configuration.php(如果启用了MultiViews，则通常是这种情况).

For example, if you have a file called configuration.php (or other extension) in root folder and you set up a rule in your htaccess for a virtual folder called configuration/ then you'll have a problem with your rule because the server will choose configuration.php automatically (if MultiViews is enabled, which is the case most of the time).

如果要禁用该行为，只需将其添加到htaccess中即可.
Options -MultiViews

If you want to disable that behaviour, you simply have to add this in your htaccess
Options -MultiViews

这样，由于禁用了内容协商，因此现在将评估您的规则.

This way, your rule will be now evaluated because content negotiation is disabled.

在某些共享主机上，谈判模块可能未启用.那将给您500错误.为避免此错误，默认情况下，您可以将指令封装在IfModule块中.

On some shared hostings, the negotiation module might not be enabled. That would give you then a 500 error. To avoid this error, you can, by default, encapsulate the directive in an IfModule block.

<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>
