📖 What Is HTTP 206?
The server is delivering only part of the resource due to a Range header sent by the client. Used for resumable downloads and video streaming.
🛡️ Security Implications
Range header abuse can cause excessive I/O on the server. Validate Range values and limit the number of ranges per request to prevent DoS.
🔍 Common Causes
Client sent a Range header to request a specific byte range (e.g., resuming a download or streaming video segments).
🔧 How to Fix
Implement proper Range header validation. Reject multipart range requests with excessive ranges.
