Unrealed thanks for help ! I solve the problem
Now, the child window send the data to parent window, using this function:

Code:

function BeginAttach()
{  	
   self.opener.document.foo.attach1.value= 'Testing1'; 
   self.opener.document.foo.submit();
   self.close();
}

In parent window source code I have this line:

Code:

<input type="hidden" name="attach1" value="Testing1">

OK.. now I want to open the child window again, and I want to send the value "Testing1" from parent to child window.

The child window has another hidden field:

Code:

<input type="hidden" name="attach1" value="">

I need to send "Testing1" from parent hidden field to chil hidden field.

Exist a way to do this without cookies or sessions?

Thank you very much !
