Using AJAX to run a webservice in the background

I basically need to do this, but unfortunately my hosting provider doesn't give me "Full Trust" so I can't run threads. Is there a way to do this using AJAX?

//Updates Information in Database
Thread threadFind = new Thread(LoadFind);
threadFind.Start();

Response.Write("Send old information to users");

I don't want my users to have to wait a开发者_Go百科t all for a response, so I can send them the old information. However, while they are on the page I want another thread (or something that works like a thread) to update the information for the next user that visits.

Thank you.

Maybe you can play with asynchronous pages:

Create a service, that is callable through HttpGet (via WCF, or a simple ASHX handler) and call it from JS (using JQuery's .ajax() or .get() methods for example).
