It's unlikely to be a server setting so much as the use of a shared resource, for example a session object that is locked by one thread until it completes, meaning that the "asynchronous" requests are in fact synchronized to protect against data corruption/loss. There is usually a way to design around such problems. What are you doing on the back end that would be shared across both requests? -- Sandy
