Rewrite rules not working properly in web.config? - node.js

Question

I have created website with React project and hosted on IIS webserver(ON VM). I have defined web.config file rules
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
</customHeaders>
</httpProtocol>
<iisnode node_env="%node_env%" nodeProcessCountPerApplication="1" maxConcurrentRequestsPerProcess="1024" maxNamedPipeConnectionRetry="100" namedPipeConnectionRetryDelay="250" maxNamedPipeConnectionPoolSize="512" maxNamedPipePooledConnectionAge="30000" asyncCompletionThreadCount="0" initialRequestBufferSize="4096" maxRequestBufferSize="65536" uncFileChangesPollingInterval="5000" gracefulShutdownTimeout="60000" loggingEnabled="true" logDirectory="iisnode" debuggingEnabled="true" debugHeaderEnabled="false" debuggerPortRange="5058-6058" debuggerPathSegment="debug" maxLogFileSizeInKB="128" maxTotalLogFileSizeInKB="1024" maxLogFiles="20" devErrorsEnabled="true" flushResponse="false" enableXFF="false" promoteServerVars="" configOverrides="iisnode.yml" watchedFiles="web.config;*.js" nodeProcessCommandLine="C:\Program Files\nodejs\node.exe" />
<handlers>
<add name="iisnode" path="server.js" verb="*" modules="iisnode" />
</handlers>
<rewrite>
<rules>
<rule name="Redirect HTTP to HTTPS" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" />
</rule>
<rule name="non-wwwtowww" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^example\.abc$" />
</conditions>
<action type="Redirect" url="https://www.example.abc/{R:1}" />
</rule>
<rule name="DynamicContent">
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True"/>
</conditions>
<action type="Rewrite" url="server.js"/>
</rule>
</rules>
<outboundRules>
<rule name="Add the STS header in HTTPS responses">
<match serverVariable="RESPONSE_Strict_Transport_Security" pattern=".*" />
<conditions>
</conditions>
<action type="Rewrite" value="max-age=31536000" />
</rule>
</outboundRules>
</rewrite>
</system.webServer>
</configuration>
The problem with the above rules is when I want to open my website directly its redirects to https://www.example.abc/server.js. I want to open https://www.example.abc .

Answer 1

The reason for redirecting to https://www.example.abc/server.js is because of your DynamicContent rule, if you want to redirect subdomain to main domain, you can refer to this rule:
<rule name="test">
<match url="^(.*)$" />
<conditions>
<add input="{HTTP_HOST}" pattern="^www.example.abc$" />
</conditions>
<action type="Redirect" url="https://www.example.abc" />
</rule>
