Question

I have a authentication cookie and I was wondering if it would be possible extract data from the cookie in the asp.net part of the code (i.e in the HTML part) .I am able to pull it out in the backend using the code below

IPrincipal p = HttpContext.Current.User;
            // p.Identity.Name : this is what we will use to call the stored procedure to get the data and populate it


            string userid = p.Identity.Name;
            Response.Write("Welcome  " +
                p.Identity.Name);
            var dbcontext = new PrepLicensingSolution2010.DAL.LicensingEntities1();
            if (userid != null)
            {
                var user = dbcontext.commissions_proc(userid);
            }

But can this be done in the front end?

Thanks

That depends on how the auth cookie is set. If HTTPOnly is used it cannot be accessed by javascript or (if the browser is secure) client side.

To access a cookie in Javascript just use

var myCookieArray = document.cookie.split(";");

And loop through the array to find the cookie you are looking for.
