What is HTTP 104 Upload Resumption Supported?
The 104 Upload Resumption Supported status code indicates that a server supports resuming interrupted uploads.
It belongs to the 1xx Informational family and is designed for modern systems that transfer large amounts of data.
Why Does Upload Resumption Matter?
Large uploads can fail because of:
- Network interruptions
- Client disconnects
- Mobile connectivity changes
- Timeouts
Without resumable uploads, clients must restart the entire transfer.
How It Helps
A resumable upload system allows a client to continue from where it stopped instead of retransmitting already uploaded data.
Common Uses
- Cloud storage platforms
- Large media uploads
- Backup systems
- Data transfer services
Why Does It Matter For DevOps?
- Reliable infrastructure design
- Large file handling
- API design
- Cloud storage systems
Summary
The 104 Upload Resumption Supported response represents the evolution of HTTP toward more reliable large-scale data transfer.
