Mod qos
mod_qos is a Quality of Service module for the Apache HTTP server implementing control mechanisms that can provide different priority to different requests.
Control mechanisms are available on two levels:
- Request level control: mod_qos controls the number of concurrent requests to a name space (URL).
- Connection level control: mod_qos controls the number of TCP connections to the web server.
The module is very useful when used in a reverse proxy in order to divide up resources to different webserver but also to prevent denial-of-service attack.
