How to make jQuery automatically retry loading () if it failed?

I am doing content replacement via jquery load () in several places on the page.

<script>
  $(document).ready(function(){
    $('#row').load('/getStudentDetails',{studentId:3});
  });
</script>

Everything works fine on my dev server. On my real server, sometimes this gives me the "request is invalid" error that I see in firebug. I think the server is becoming overloaded, or maybe some kind of caching module gets confused with a few requests. I will try to figure this issue out separately, but also just want him to repeat the same query (once) if he fails. Is there a way to use jQuery for this?
