I need to be able to set the domain property of the document object in
order to use cross-frame scripting (since our app is separated across
two machines).

Anyways, I tried the following in VBScript code (in an initialization
function which is called once the body is loaded):

sub InitPage

   document.domain = "mydomain.com"

end sub

However, I got an "Invalid Argument" error from this.  Can someone
explain why or how I go about doing something like this?  

Thank you,

Mark Gabriel
