How to redirect from host name to domain name using url rewrite

Question

I have a site which is accessible both by these urls inside my domain:

http://test 
http://test.mydomain.com

I'm trying to set up a redirect from http://test to http://test.mydomain.com using url rewriting, this is the rule I have at the moment:

<rule name="domain redirect" enabled="true" stopProcessing="true">
    <match url="^test(.*)$" />
    <action type="Redirect" url="http://test.mydomain.com/{R:0}" appendQueryString="true" />
</rule>

But it creates redirect loop. I know there is something small I'm missing, can anyone help?

Thank you

You can create a file (if it's not already created) called ".htaccess" without quotes and put in the following code (changing "test" and "mydomain", of course):

RewriteEngine On
RewriteCond %{HTTP_HOST} ^test\.com$ [NC]
RewriteRule ^(.*)$ http://test.mydomain.com$1 [L,R=301]
