YouTube API v2.0 – Resumable Uploads
• Based on Google Gears protocol
• Invents new http code 308 Resume Incomplete
• Uses PUT to “query” upload status
• Abuses “Content-Range”, “Range” headers
• Not meant for interoperability
![Page 35: tus.io – Resumable file uploads for web and mobile apps by Felix Geisendörfer](https://reader036.fdocuments.in/reader036/viewer/2022081721/5558446ed8b42ac6078b51f9/html5/thumbnails/35.jpg)

Amazon S3
• Multipart API
• Complicated, hard to implement for clients, hard for servers
• 5 MB chunk size limit
• REST? What’s REST?
• Not meant for interoperability

@felixgefelixge
resumable.js
• Uses multipart/form-data, not RESTful
• Requires lots of small chunk requests (ovhead)
• Poorly specified protocol
• Still: Probably best open source solution out there right now
