web.config file

I need a rewrite rule and can't get the syntax to remove the www OR ANY subdomain from domain.com
so www.domain.com or ww3.domain.com or xyz.domain.com will all rewrite to domain.com

Use the negate="true" flag to redirect anything not domain.com to domain.com like in the canonical host name example here

I see that I rewrote my question and left out a crucial bit

Is there a way to use this to rewrite multiple domains in one rule?
i.e. "domain1.com|domain2.com|domain3.net"
and the action is to rewrite back to origin domain?
www.domain.com would be domain.com & www.domain3.net would be domain3.net

Thanks ...

Because of multiple domains the rule you pointed to doesn't work out.
All sites relocate to the domain in the first rule for some reason.
It works for just the one domain though.

I am using this which seems to work for multiple domains:

                        <rule name="SEO - HTTP canonical redirect" stopProcessing="true">
                              <match url="^(_*)(.*)" />
                              <conditions logicalGrouping="MatchAll" trackAllCaptures="true">
                                    <add input="{HTTP_HOST}" pattern="^www\.(.*)" />
                                    <add input="{HTTP_METHOD}" pattern="GET" />
                                    <add input="{SERVER_PORT}" pattern="80" />
                              <action type="Redirect" url="http://{C:1}/{R:2}" />

That should work. You could also use something like ^ww?\.(*.)
Many different ways to do regex
