Can you stop ASP.NET from changing IDs so that it can be used in jQuery

I have this label control in my web page using asp.net

< asp:Label ID="Label1" runat="server" Text="test">< /asp:Label >
And when the page rendered the id of the control changes to something like this

< span id="ctl00_ContentPlaceHolder1_Label1">test< /span >
How can I stop asp.net from changing IDs in order to perform a jQuery operation like this

$('#label1').html(xml);

How to do a Forms Authentication across Sub-Domains

Is it possible to authenticate users across sub-domains when the authentication takes place at a sub-domain instead of the parent domain?

For example:

User logs into site1.parent.com, and then we need to send them to reporting.parent.com.

Can I authenticate them to the reporting site even though the log-in occured at a sub-domain?
