DSM 6.2, IIS Reverse Proxy and /webman not rewrite

[RainbowShaggy]

Hello,

 

so I'm successfully set up Reverse Proxy on IIS today to access to my DSM through my own domain and without port. And I found an interesting thing. Everything works great except when I'm redirect to https://mydomain.com/webman/index.cgi or https://mydomain.com/webman. I found this, when I playing with Office. When I wanted to create a new document, every time it redirected me to login page without rewrite to address https://ipaddress:5001/webman/index.cgi and I don't know why. Why every other pages works and this don't? Even If I create Portal Application with alias rewrite works.

 

Here's my rewrite rules:

<rewrite>
  <rules useOriginalURLEncoding="false">
    <clear />
    <rule name="HTTP/S to HTTPS Redirect" enabled="true" stopProcessing="true">
      <match url="(.*)" />
      <conditions logicalGrouping="MatchAny">
        <add input="{SERVER_PORT_SECURE}" pattern="^0$" />
      </conditions>
      <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" />
    </rule>
    <rule name="ReverseProxyInboundRule2" enabled="true" stopProcessing="true">
      <match url="(.*)" />
      <action type="Rewrite" url="https://192.168.1.240:5001/{R:1}" appendQueryString="true" logRewrittenUrl="true" />
    </rule>
  </rules>
</rewrite>

 

Thanks for your help and suggestions.
