if (!formsauthentication.cookiessupported) {     //if authentication ticket specified not use cookie, set in uri     formsauthentication.setauthcookie(encrypetedticket, createpersistentcookie); } else {     //if authentication ticket specified use cookie, wrap within cookie.     //the default cookie name .aspxauth if not specified      //in <forms> element in web.config     httpcookie authcookie = new httpcookie(formsauthentication.formscookiename, encrypetedticket);      //set cookie's expiration time tickets expiration time     if(ticket.ispersistent)         authcookie.expires =ticket.expiration ;      ////set cookie in response     httpcontext.current.response.cookies.add(authcookie); }
