Url 将第一个路径段重写为子域

Question

I'm trying to do the below with a rewrite. From my attempts so far, it doesn't appear possible since I don't think I have access to rewrite the host.

domain.com/sub/web/mypage needs to become sub.domain.com/web/mypage

Essentially trying to do the opposite of this: URL Rewrite city.domain.com to domain.com/city

Was hoping to figure out a rewrite or something so I don't have to spend weeks fixing routes in a legacy webforms application that's very coupled to the expected subdomain url pattern.

My thought was to rewrite on a proxy server and send to the server farm with the "old" subdomain url and it would maybe "just work".

Do you want to redirect from https://doman.com/sub/web/mypage to https://sub.domain.com/web/mypage ? if so, you can try this rule:

<rule name="test1" stopProcessing="true">
   <match url="(.*)" />
      <conditions>
           <add input="{HTTP_HOST}" pattern="^domain.com$" />               
           <add input="{HTTPS}" pattern="on" />
           <add input="{REQUEST_URI}" pattern="^/sub/web/mypage" />
      </conditions>
   <action type="Rewrite" url="https://sub.domain.com/web/mypage" logRewrittenUrl="true" />
</rule>
