I would like to do a drag and drop of few elements within the page (its like rearranging a page resource) and do a submit of the page after the changes are made to the page. I would like to know much of the response is consumed for it.
I guess that when you will make this drag and drop there's nothing that will be sent to the server. It's only when you will submit the page. In that case, NeoLoad will be able to capture that request/response so you can replay it.
So basically, NeoLoad won't be able to capture anything related to your drag and drop if nothing is exchanged between your browser and your server.
