How do I do an AJAX request for a project file using a string for the name?

Is this possible? I'm basically looking for a "Create object by name" method but for loading project files with AJAX.

Or is there a way to get the URL of a project file without using JS so I can use the AJAX plugin's "Request URL" action? My project is currently all event sheets all the time, with no JS, and I'd like to keep it that way if I can.

You can use AJAX "Request URL"

and just enter as a URL the "FileName.Extension "
