I'm having a problem like a file upload code.
The user begins to upload files through the site (for large files. Like Wetransfer) Showing percentage loading with Ajax.
When completed, showing warning.
But the problem starts here.
Because files are huge, it takes time to move to the appropriate folder and ziping.
If the user closes the browser in this process, the process can not be completed.
Even users close the browser, how do I ensure that the operation continues.
I tried to ignore_user_abort. But I was not successful.
