Since I want the url to change from "domain.com" to "WWW.domain.com"

Is this correct ?

 <if header="HOST" match="^(http://domain.com)$">
  <redirect name="SiteCanonical" url="^(.*)$" to="http://www.domain.com" />
</if>

Yes, this should work.

its not working....your previous code is working and making www.domain.com to domain.com but like i mentioned i want opposite....please double check on your end ?

Sorry didn't see this part, change http://domain.com to domain.com.

it is working but seems like it is somehow affecting other things...

Now it does what it is supposed to do...if I type this in address bar "mydomain.com" it becomes "http://www.mydomain.com":

But the problem is...

Like, now I am not able to see pages that I added from administration side...

If I go to http://mydomain.com/MyNewPage.aspx,,, it redirect me to "www.mydomain.com"

why ?

Hello,

URL rewriting in MonoX is based on UrlRewriter.NET. You would need to check their support forums regarding this matter.
