url重写后如何知道原始url？

I have url rewrite rules which redirect www.domain2.com to a subfolder under the root of a domain1.com (let's call this folder subproject). In my controller, I need to construct a URL to the original non modified path but the Request.Url properties (like AbsoluteUri or LocalPath) always contain the subproject subfolder.

我有url重写规则，将www.domain2.com重定向到domain1.com根目录下的子文件夹（让我们调用此文件夹子项目）。在我的控制器中，我需要构建一个指向原始未修改路径的URL，但Request.Url属性（如AbsoluteUri或LocalPath）始终包含子项目子文件夹。

In other words, if the user typed:

换句话说，如果用户键入：

www.domain2.com/controller/action

urlrewrite makes it:

urlrewrite使它成为：

www.domain1.com/subproject/controller/action

and I wish to reconstruct the original url:

我希望重建原始网址：

www.domain2.com/controller/action

I could hardcode the removal of subproject from the url and begin the url with domain2 but I need a generic piece of code because this url reconstruction will be in a reusable library. domain2 could be in the settings of my app but what about the subfolder?

我可以硬编码从url中删除子项目并使用domain2开始url但我需要一个通用的代码段，因为这个url重建将在一个可重用的库中。 domain2可能在我的应用程序的设置，但该子文件夹呢？

In reference, here is the rewrite rule:

在参考中，这是重写规则：

<rewrite>
    <rules>
        <rule name="Redirect to subproject">
            <match url=".*" />
            <conditions>
                <add input="{HTTP_HOST}" pattern="^(www.)?domain2.com" />
                <add input="{PATH_INFO}" pattern="^/subproject/" negate="true" />
            </conditions>
            <action type="Rewrite" url="\subproject\{R:0}" />
        </rule>
    </rules>
</rewrite>

Thank you

谢谢

You should be able to find it in Request.RawUrl.

您应该能够在Request.RawUrl中找到它。

Here is a good way to get the current directory even when using rewrite.

即使使用重写，这是获取当前目录的好方法。

I needed this to cache some resources in localStorage for an offline web app. With asp.net mvc, the page parameters are written as subdirecties under a page which causes the relative paths to change. Therefore, I needed the absolute path as a key for the resource in the localStorage.

我需要这个来缓存localStorage中的一些资源以用于离线Web应用程序。使用asp.net mvc，页面参数被写为页面下的子目录，这会导致相对路径发生变化。因此，我需要绝对路径作为localStorage中资源的关键。

Anyway, here it is:

无论如何，这里是：

        var applicationRoot = new System.Uri(Request.Url, Href("~"));
        var rawURl = Request.RawUrl;
        var rawUrlAbsolute = new System.Uri(serverRoot, rawURl);
        var relativeToCurrentPath = Href("SOMETHING_DOESNT_MATTER/../");
        var clientPathAbsolute = new System.Uri(rawUrlAbsolute, relativeToCurrentPath);
        var clientPathAbsoulteStr = clientPathAbsolute.AbsoluteUri;

This took me many attempts to figure out. Here is an example using my website:

这让我想出了许多尝试。以下是使用我的网站的示例：

The path without rewriter

    //  applicationRoot         = http://www.toldpro.com/
    //  rawURl                  = /Apps/GreekBible/App/A/B/C
    //  rawUrlAbsolute          = http://www.toldpro.com/Apps/GreekBible/App/A/B/C 
    //  relativeToCurrentPath   = ../../../
    //  clientPathAbsolute      = http://www.toldpro.com/Apps/GreekBible/
    //  clientPathAbsoulteStr   = http://www.toldpro.com/Apps/GreekBible/

The path rewriten to a subdomain

    //  applicationRoot         = http://greekbible.toldpro.com/Apps/GreekBible/
    //  rawURl                  = /App/A/B/C
    //  rawUrlAbsolute          = http://greekbible.toldpro.com/App/A/B/C 
    //  relativeToCurrentPath   = ../../../Apps/GreekBible/
    //  clientPathAbsolute      = http://greekbible.toldpro.com/Apps/GreekBible/
    //  clientPathAbsoulteStr   = http://greekbible.toldpro.com/Apps/GreekBible/

The rewrite rule:

For more information about this, the following is the rewrite rule I used:

有关此内容的更多信息，以下是我使用的重写规则：

// Rewrite: 
// http://greekbible.toldpro.com/App/* (Client)
// to
// http://www.toldpro.com/Apps/GreekBible/App/* (Actual)

    <rule name="Subdomain rewriter" stopProcessing="true">
      <match url="App/(.*)" />
      <conditions>
        <add input="{HTTP_HOST}" pattern="^www\.toldpro\.com$" negate="true" />
        <add input="{HTTP_HOST}" pattern="^greekbible\.toldpro\.com$" />
      </conditions>
      <action type="Rewrite" url="/Apps/GreekBible{URL}" />
    </rule>
