Redirect Non-WWW to WWW in Web.config (Except one spesific subdomain)

On my Windows 2012 server I have installed the URL Rewrite module in IIS. I have followed this guide to redirect non-www to www in web.config: http://www.surfingsuccess.com/asp/iis-url-rewrite.html#.VF6GBid0yAU

So far, so good!

The only problem is that we also host the subdomain "api.mysite.com". This API stops working when I apply the <rewrite> code in web.config. My question is: How can I change the <rewrite> code below to redirect non-www to www, except for the subdomain "api.mysite.com"?

    <rewrite>
      <rules>
        <rule name="RedirectToWWW" stopProcessing="true">
          <match url=".*" ignoreCase="true" />
          <conditions>
            <add input="{HTTP_HOST}" pattern="^mysite.com$" />
          </conditions>
          <action type="Redirect" url="http://www.mysite.com/{R:0}" redirectType="Permanent" />
        </rule>
      </rules>
    </rewrite>

Could you add a new rule as the first rule matching the specific URL in question and use the action type of None?

I don't know? I guess it should be possible to make an exception so that "api.mysite.com" never is redirected. I tried using "negate" in <conditions>, then "api.mysite.com" worked as it should, but mysite.com is not always correct redirected to www.mysite.com.

Do you mean something like this?

<rule name="block" stopProcessing="true">
    <match url="^api.mysite.com$" />
    <action type="None" />
</rule>

That appears to be correct, based on Microsoft's documentation.

I tried it, but the subdomain does not work.

    <rewrite>
      <rules>
        <rule name="RedirectToWWW" stopProcessing="true">
          <match url=".*" ignoreCase="true" />
          <conditions>
            <add input="{HTTP_HOST}" pattern="^mysite.com$" />
          </conditions>
          <action type="Redirect" url="http://www.mysite.com/{R:0}" redirectType="Permanent" />
        </rule>
        <rule name="API" stopProcessing="true">
          <match url="^api.mysite.com$" ignoreCase="true" />
          <action type="None" />
        </rule>
      </rules>
    </rewrite>

I also tried "negate" without Luck

    <rewrite>
      <rules>
        <rule name="RedirectToWWW" stopProcessing="true">
          <match url=".*" ignoreCase="true" />
          <conditions>
            <add input="{HTTP_HOST}" pattern="^mysite.com$" />
            <add input="{HTTP_HOST}" pattern="^api.mysite.com$" negate="true" />
          </conditions>
          <action type="Redirect" url="http://www.mysite.com/{R:0}" redirectType="Permanent" />
        </rule>
      </rules>
    </rewrite>

Retry the first attempt, but switch the order of the rules. I believe the rules engine will find the first rule that satisfies the condition, and in your first attempt, the .* would match anything and, therefore, would always be used.

<rule name="Redirect to HTTPS" stopProcessing="true">
<match url="(.*)" />
<conditions><add input="{HTTPS}" pattern="^OFF$" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="SeeOther" />
</rule>

Shaun Kline: Unfortunatly that did not help either, api.mysite.com still stop working when I add the <rewrite> code in web.config (mysite.com).

I think this is pretty strange since api.mysite.com is one site in IIS, and mysite.com is another site in IIS. When I user url rewrite on one site (mysite.com), why does that effect another site (api.mysite.com). They also run in separate application pools.

Is it possible to make a rule that only redirects to www.example.com if the input doesn't start with www. or api.?

Actually, there was nothing wrong with my rewrite code. The reason why the API stopped working was because it had a referance to the top domain of the site (example.com), this caused a conflict with the rewrite code. After changing the referance to the www -version of the doman (www.example.com) everything worked fine.
