How can we rewrite an URL in Azure Webapp

Question

I have a simple wildcard routing rule I want to apply for my Azure web app.

<rule name="MyRule">
  <match url="*" />
  <action type="Rewrite" url="/index.html" />
</rule>

Do I have any option here given I can't RDP into the machine and fiddle with IIS? This is not an ASP.Net website, it's a simple SPA application.

You need to create a web.config file in your wwwroot folder and put the relevant config entries there.

Here's an example of an web.config rule, to give you an idea of what it should look like.

The below example redirect the default *.azurewebsites.net domain to a custom domain (via http://zainrizvi.io/2016/04/07/block-default-azure-websites-domain)

<configuration>
  <system.webServer>  
    <rewrite>  
        <rules>  
          <rule name="Redirect rquests to default azure websites domain" stopProcessing="true">
            <match url="(.*)" />  
            <conditions logicalGrouping="MatchAny">
              <add input="{HTTP_HOST}" pattern="^yoursite\.azurewebsites\.net$" />
            </conditions>
            <action type="Redirect" url="http://www.yoursite.com/{R:0}" />  
          </rule>  
        </rules>  
    </rewrite>  
  </system.webServer>  
</configuration>
