mod-bw is an Apache 2 module provided to solve the problem of limiting users’ and virtual hosts’ bandwidth usage. The current versions can set virtual hosts’ and users’ bandwidth quotas, maximal download speed, requests-per-second speed and the maximal number of simultaneous IP connections.
mod-bw Features:
* Lightweight bandwidth limiting module for Apache2
* per-user bandwidth limiting
* per-virtual host bandwidth limiting
* per-destination bandwidth limiting
Limiting:
* Bandwidth total usage (bandwidth quota)
* Maximal download speed (bandwidth throttling)
* Maximal requests-per-second speed
* Maximal simultaneous IP connections
* Support for virtual hosts
* Support for defined users
