IIS 服务器 url 重写

Question

For example, I have a domain example.com and my server IP is 1.1.1.1 that is running Microsoft IIS server on Windows Server 2016 Datacenter
The DNS record is A *.example.com 1.1.1.1
I want to make the server, 1.1.1.1 display the contents under C:\inetpub\*
If the directory doesn't exist, the server should return a 404 error.

For example:

• The file system:

|--C:\
    |-- inetpub\
        |-- a
        |-- b
        |-- c

will results:

• a.example.com show contents under C:\inetpub\a
  
• b.example.com show contents under C:\inetpub\b
  
• c.example.com show contents under C:\inetpub\c
  
• d.example.com return HTTP/1.1 404 Not Found
  

Thanks.

Please map these folders as virtual directory under your website.

For example: /a->c:\inetpub\a. /b->c:\inetpub\b.

Then you can easily rewrite a.example.com/test.aspx to a.example.com/a/test.aspx. If the folder does not exist. Then d.example.com/d/ will just return 404.

<rule name="rewrite">
    <match url="(.*)" />
        <conditions>
           <add input="{HTTP_HOST}" pattern="(.*)\.example\.com" />
        </conditions>
    <action type="Rewrite" url="{C:1}/{R:1}" />
</rule>
