Check if the requested user has admin privileges
<p>In a web application, is there any way to check the requested user has got admin privileges.
Is it possible? Can you suggest one method?</p>

<p>For example: a front-end user requests a page in my application. I want to know whether the user that made the request has admin privileges in his client machine. I have to check whether he is logged in with an admin privileged account in the system.</p>

<p>I need the privileges of logged in user to the system not to my application , my application doesn't have a login. One user just request my home page or any other page and i just want to know that user is logged into his PC with an admin account or not?</p>
