HTTP Request Throttle

Setting the HTTP Request Throttle

Use the set http-request throttle command to configure a per-session throttle on the rate at which HTTP requests from that session are handled before authentication. A new session begins with max_requests requests enabled. Every request uses one from a pool of available requests until there are no requests available in the pool. Requests are allocated to the session at request_rate requests per second.

Note: This command has no effect on authenticated subscribers.

To configure a per session throttle on the rate at which HTTP requests from that session are handled before authentication, use this command:

set http-request-throttle max_requests [request_rate]

For example, to enable an HTTP request throttle for each unauthenticated session, starting with 10 requests, and with requests available to that session at one request per second, use:

sms2000% set http-request-throttle 10 1

If the subscriber generates 11 HTTP requests in less than one second, it is ignored. After using all available requests, only 1 request per second is handled and additional requests are ignored.

Deleting the HTTP Request Throttle

To disable the HTTP request throttle for sessions not yet authenticated, use this command:

delete http-request-throttle

For example to turn off the HTTP throttle request setting, type:

sms2000% delete http-request-throttle
