how to redirect website to main url?

Question

Hey Guys,

I have created React nodejs app and hosted the app on the azure VM IIS webserver. I have defined below set of rules in web.config file

<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="DynamicContent">
                     <conditions>
                          <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True"/>
                     </conditions>
                     <action type="Rewrite" url="server.js"/>
                </rule>

              <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="^xyz\.com$" />
                </conditions>
                <action type="Redirect" url="https://xyz.com/{R:1}" />
            </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>

whenever I have tried to open my website directly from the browser its redirects to https://www.xyz.com/server.js. I want to redirect my website to https://www.xyz.com. I have defined a rewrite rule for server.js (It's important for node js applications). Please help me guys to resolve this issue.

Thanks, Guys in advance.

@Sudesh Sharma ,

I see a negate pattern in the web.config (1st rule). A pattern can be negated by using the negate attribute of the <match> element. The rule action is performed only if the current URL does not match the specified pattern when this attribute is used. This can be used to specify a condition that checks if the requested URL is NOT a file - :
<add input="{REQUEST_FILENAME}" matchType="isFile" negate="true">

I feel, this condition is making the app redirect to server.js. Do you require the above attribute in your web.config? If not, can you comment and check if the URL redirection is working as expected.

I hope that helps.
