Redirecting

Hi All;

I have a problem with NopCommerce redirecting method
My Host does not support redirecting and i have a shared host. The only thing i can do is to make a domain pointer (Alias) then i have to redirect the domain pointer which this part is my issue

I'm using NopCommerce 1.8 and it is installed on root of my host.
Suppose that i have a domain pointer called www.Domain1.com then i would like to redirect it to a page on my nopcommerce application. I assume i have to put the following code somewhere in Defult.aspx or web.config of my NopCommerce application. Would you please tell me where can i put this code?


<%
If InStr( UCase(Request.ServerVariables("SERVER_NAME")), UCase("www.Domain1.com") ) > 0 Then
Response.Redirect("//category/x1x1x1.aspx")
End If
%>

Many Thanks in Advance and Happy New Year!
