I had a nightmare recently where files that I uploaded by FTP looked ok at first but were actually incorrect.
They looked ok at first because it seems there is a delay between file upload and when the changes are shown.
I’ve tried hard resets and cache clearance but nothing seems to show the changes immediately.
I guess it has something to do with propagation.
Is there a developer tool to speed this up?
Is this something to do with the FTP client or the webhosts?
