I am looking for a way to make asynchronous calls with VBScript. Is this even possible? Can we start a worker thread? Any other possibilities or workarounds?

Do you mean AJAX calls with the XMLHttpRequest object in an ASP page? Just curious; why VB Script?

We are looking to speed up the post back of a page that process a form. Basically we want to be able to start a worker thread to complete the actual processing and also asynchronously display a confirmation message.

Currently, the confirmation message is displayed after the form processing in completed.

Why VBScript? Our framework was built using Classic ASP (VBScript)
