Answer 1

This is what you would want in your php IF THIS WERE A REGULAR REQUEST, NOT AN AJAX

if (isset($_SESSION)) doSomething();  
else header("Location: otherUrl");

Since this is an Ajax call, you are not passing control to the php, but just trying to get a response that (likely) fills a particular section of your page. You do not mention what jQuery ajax function you use, but it matters. I would imagine you are using either $.get() or $(element).load() ??

Without knowing the particulars, this is my best suggestion for you.

Ajax call: $.get(url, callbackFunc);

php:

if(isset($_SESSION)) echoSomething()   else echo("redirect");

callbackFunc:

function(data)
{ if (data == "redirect") window.location = otherUrl;
   else 
   $("#desiredElement").html(data);
}
