redirect asp.net 2.0 pages

Hi there

I have a server set up and am pointing .co.uk domain names to it.

In order to redirect the request when it hits my server, i have added this code to the iisstart page.


If HTTPHost = "www.domain.co.uk" then
    Response.Redirect ("http://www.domain.co.uk/folder")
End If

Now, i would prefer not to show the folder in the line so that pages are seen in the browser as www.domain.co.uk/default.aspx etc.,

Is there a way of doing this.
I am also conscious of the effect of the redirect might have on google rankings.

Any advise, much appreciated.

The server is hosting windows 2000 small business server if this helps.

thanks.
