Hi,

Thanks for the reply. I added the leading dot as suggested by you, but still getting the Invalid argument error.

function openUrl()
{
    alert(document.domain);
    document.domain=".xyz.com";
    alert(document.domain);

    window.open ("http://Server2/testpage.asp", target="mainframe");
}

We only use IE, so i dont have to worry about Netscape. Is document.domain a read only property?

Thanks

i tihink with this u need to use fully qualified domain name.

After execution of that statement, the page would pass the origin check with http://www.xyz.com/

also could u check this post.

I tried to set the document.domain property as described in the above links, but it did'nt help. It is not taking any thing.

i tried

//Server 1:
//servername1.abc.xyz.com
//Server 2:
//servername2.abc.xyz.com

function openUrl()
{
    alert(document.domain);
    document.domain=".xyz.com";
    alert(document.domain);

    window.open ("http://Server2/testpage.asp", target="mainframe");
}

I tried all of these

   document.domain="xyz.com";  //gives Invalid argument error
   document.domain=".xyz.com"; //gives Invalid argument error
   document.domain="abc.xyz.com";  //gives Invalid argument error
   document.domain=".abc.xyz.com";   //gives Invalid argument error
 
   document.domain=".abc.xyz";   //gives Invalid argument error

   document.domain="document.domain";   //Does not give error
   alert (document.domain); gives machine name

   document.domain="machine name";   //Does not give error
   alert (document.domain); gives machine name

are there any properties that need to be set?

Thanks

something silly missing.
could u try
document.domain='.abc.xyz.com';     <--- with sinle quote it is just guess so try all the option as u have tried above statement.

Actually, the url used to access should be fully qualified. i.e

document.domain="xyz.com"; works for
http://servername1.abc.xyz.com/testpage.asp

and gives invalid argument error with this
http://servername1/testpage.asp as i was using.

The origin check as mentioned by you might have been failing in the later case.

By default, the domain property is the same as the hostname of the web server from which the document was loaded. You can set this property, but only to a string that is a valid domain suffix of itself. Thus, if domain is the string "home.xyz.com", you can set it to the string "xyz.com", but not to "home.xyz", "abc.com" or "abc.xyz.com".

If two windows contain scripts that both set their domain to the same value, then the access issue will be resolved for these two windows/frames and in each of windows/frames may read properties from the other.
