Azure IIS windows redirect not working

[18AX]

Hi everyone,

App router with locales works fine locally but adds 'pipe/8418b788-6ad6-4dea-95cb-xxxxxxxxxxxx/' to the URL when deployed to Azure, as if the port is added to the url. I feel like it is looping infinitely because the 'pipe/8418b788-6ad6-4dea-95cb-xxxxxxxxxxxx/' is adding multiple times in the url like

https://example.com/en/pipe/8418b788-6ad6-4dea-95cb-xxxxxxxxxxxx/en/pipe/8418b788-6ad6-4dea-95cb-xxxxxxxxxxxx/en/pipe/8418b788-6ad6-4dea-95cb-xxxxxxxxxxxx/......

Example of the redirect from my browser

<https://example.fr/en//pipe/536cde08-ab74-4ddb-bdef-41xxxxxxxxxx/fr>; rel="alternate"; hreflang="en", <https://example.fr/fr//pipe/536cde08-ab74-4ddb-bdef-41xxxxxxxxxx/fr>; rel="alternate"; hreflang="fr"

My web.config:

<configuration>
  <system.webServer>
    <!-- Visit http://blogs.msdn.com/b/windowsazure/archive/2013/11/14/introduction-to-websockets-on-windows-azure-web-sites.aspx for more information on WebSocket support -->
    <webSocket enabled="false" />
    <handlers>
      <!-- Indicates that the server.js file is a node.js site to be handled by the iisnode module -->
      <add name="iisnode" path="server.js" verb="*" modules="iisnode"/>
    </handlers>
    <rewrite>
      <rules>
        <!-- Do not interfere with requests for node-inspector debugging -->
        <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">
          <match url="^server.js\/debug[\/]?" />
        </rule>

        <!-- First we consider whether the incoming URL matches a physical file in the /public folder -->
        <rule name="StaticContent">
          <action type="Rewrite" url="public{REQUEST_URI}"/>
        </rule>

        <!-- All other URLs are mapped to the node.js site entry point -->
        <rule name="DynamicContent">
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True"/>

          </conditions>
          <action type="Rewrite" url="server.js"/>
        </rule>
      </rules>
    </rewrite>
    
    <!-- 'bin' directory has no special meaning in node.js and apps can be placed in it -->
    <security>
      <requestFiltering>
        <hiddenSegments>
          <remove segment="bin"/>
        </hiddenSegments>
      </requestFiltering>
    </security>

    <!-- Make sure error responses are left untouched -->
    <httpErrors existingResponse="PassThrough" />

    <!--
      You can control how Node is hosted within IIS using the following options:
        * watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
        * node_env: will be propagated to node as NODE_ENV environment variable
        * debuggingEnabled - controls whether the built-in debugger is enabled

      See https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/web.config for a full list of options

    <!--<iisnode watchedFiles="web.config;*.js"/>-->
  </system.webServer>
</configuration>

Do you have any idea how to solve this ?

Thank you

Maybe this is related: #1556. I unfortunately don't have any experience with Azure IIS.

Thank you for your reply. It looks similar to this problem: https://learn.microsoft.com/en-us/answers/questions/1354409/nodejs-app-in-azure-windows-app-service-with-iisno. We solved it by moving to a Linux instance.
