Overview

This document describes how to limit the URL upload and download speeds.

Single-URL Speed Limits

Description

The speed range is 819200 to 838860800 (in bit/s), that is, 100 KB/s to 100 MB/s. If a value is not within this range, 400 will be returned.

Sample 1. Limiting single-URL speed on uploads
