Web.config rewrite rules adding additional / on URLS that contain www

See more:

ASP.NET

web.config

I have a website that has an SSL that I automatically remove the beginning www from when a user visits our site.

So when a user types in www.my-example.com they are redirected to https://my-example.com

Here is the rule I wrote to achieve this.

<rule name="Remove www.">
   <match url="(.*)" />
   <conditions>
     <add input="{HTTP_HOST}" pattern="^www.(.*)" />
   </conditions>
   <action type="Redirect" url="http://{C:1}/{URL}" />
 </rule>

This works fine in most cases but I'm running into an issue. We have many outside sources linking to individual pages we made like this: https://www.my-example.com/example-post

It correctly removes the www but appends a second / before the example post. So the above url would redirect to https://my-example.com//example-post

I need this to not happen. Any suggestions?

What I have tried:

I only have 2 rewrite rules in my web.config file. Here they are as is

<rule name="Force HTTPS Redirection" enabled="true" stopProcessing="true">
  <match url="^$" ignoreCase="false"/>
  <conditions>
    <add input="{HTTP_HOST}" pattern="localhost" negate="true" />
    <add input="{HTTPS}" pattern="^OFF$"/>
  </conditions>
  <action type="Redirect" url="https://{HTTP_HOST}/" redirectType="Permanent"/>
</rule>
<rule name="Remove www.">
  <match url="(.*)" />
  <conditions>
    <add input="{HTTP_HOST}" pattern="^www.(.*)" />
  </conditions>
  <action type="Redirect" url="http://{C:1}/{URL}" />
</rule>
