将多个 IIS7 重写规则(重定向)合二为一 [英] Combine Multiple IIS7 Rewrite Rules (Redirects) Into One

问题描述

我正在使用 iis7 的 URL Rewrite 模块来完成几件事:

I am using iis7's URL Rewrite module to accomplish several things:

• 从非 www 到 www 的 301 重定向规则
• 301 将规则 .info 重定向到 .com(移动到我域的 .com 版本)
• 301 从旧页面重定向规则，例如/page-name.asp 到/page-name

我已经能够将前两项合并为一个规则，第三项是它自己的规则.问题是在请求如下url的情况下会生成两个301重定向:

I have been able to combine the first two into one rule, and the 3rd item is it's own rule. The problem is that two 301 redirects are generated in a case of requesting a url like:

site.info/page-name.asp/

site.info/page-name.asp/

首先执行 301 以:

First a 301 is done to:

www.site.com/page-name.asp(例如添加 www 并且 .info 转到 .com)

www.site.com/page-name.asp (e.g. www is added and .info goes to .com)

然后第二个 301 是从那里完成的:

Then a second 301 is done from that to:

www.site.com/page-name

www.site.com/page-name

我的问题是:如何将这些组合起来，以便只发生一个 301 重定向而不是两个?以下是当前位于我的 web.config 中的两个规则:

My question is: how can I combine these so that only ONE 301 redirect occurs instead of two? Here are the two rules as they currently sit in my web.config:

<rule name="SEO - 301 Redirect - .info to .com AND force WWW" stopProcessing="false">
    <match url="(.*)" ignoreCase="true" />
    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
        <add input="{HTTP_HOST}" pattern="^site.info$" />
    </conditions>
    <action type="Redirect" url="{ToLower:http://www.site.com/{R:1}}" redirectType="Permanent" />
</rule>
<rule name=".aspVersion-to-friendlyvia301" stopProcessing="false">
        <match url="(.*).asp" />
        <action type="Redirect" url="{R:1}" />
</rule>

推荐答案

我似乎找到了自己问题的答案.这是一个小技巧，但完成了所有必需的 url 转换(例如删除尾部斜杠、非 www 到 www、toLowerCase、删除目录的默认文档以及任何其他必要的重定向，例如页面名称更改).

I seem to have found the answer to my own question. It is a bit of a hack but accomplishes all required url transformations (e.g. trailing slash removal, non-www to www, toLowerCase, removal of default document for directories, and any other redirects necessary such as a page name change).

我所说的问题实际上被称为301重定向链接"，解决方案相当优雅，在这里:

The problem I was talking about is actually called "chaining of 301 redirects", and the solution is presented rather elegantly, here:
