It is not possible. The reason behind this is that http is a stateless protocol. When we send any request over http it creates a temporary session & maintain state for that request only. Once connection with server break, all the information on server is lost regarding state. The developer has to manually manage the state.

In this case when you are sending a file, the file uploaded in packets & server keeps it in memory till complete file is not uploaded. After receving If connection break, the server release memory & anything uploaded will be lost.

It is mandatory to upload once again.

I hope this would answer your query. Let me know if you need more clarity on this.
