I have orders.something.com and hr.something.com. How can I login into both systems?
<p>I have a site orders.something.com and other site hr.something.com. My 1st question should I create different applications for these in VS 2010 or I can run it inside single application too? Secondly, if I create 2 applications how can I establish login into both system? So for example if he is logged into something.com, he is authenticated into orders.something.com as well as hr.something.com?</p>

<p>Thanks in advance :)</p>
