session problem

[eluser]paulon[/eluser]
nice it fixed my problem regarding direct access to scripts

Code:

//javascript
var obj = {
get_user_online: function(){
   var url="<?=base_url()?>index.php/generals/getuseronline";
   $.post(url,{isAllowed:1},
      function(data){
         document.getElementById("divuserlist")[removed] = data;
      });        
}
}

that calls in

Code:

//php script
function getuseronline(){    
   if($_POST['isAllowed']>0){        
      $strReturn = 'Hello world';
   }else{
      $strReturn = 'No direct access allowed';
   }
echo $strReturn;
}

so when ever the link type in directly into the browser "http://localhost/CI/index.php/generals/getonlineuser"
it returns a "No direct access allowed'
