How to update a HTML progress tag during an asp-classic postback

[Marvin Skow5E3D]

I currently have a web page for my company that sends a JavaScript \[code\]XMLHttpRequest\[/code\] back to the server to run a process and return data via XML. This server side process is written in classic ASP (to match up with the rest of the web portal), and can take anywhere from 5 seconds to a couple of minutes depending on how many purchase orders need to be generated.If I have a \[code\]<progress>\[/code\] element (or any other kind of element for that matter) located in the client side web page, is there a way for me to update this element during execution of the server side ASP process that's generating the XML results?
