Package io.undertow.server.handlers

Class RequestLimit

java.lang.Object
io.undertow.server.handlers.RequestLimit
public class RequestLimit extends Object
Represents a limit on a number of running requests.

This is basically a counter with a configured set of limits, that is used by RequestLimitingHandler.

When the number of active requests goes over the configured max requests then requests will be suspended and queued.

If the queue is full requests will be rejected with a 513.

The reason why this is abstracted out into a separate class is so that multiple handlers can share the same state. This allows for fine grained control of resources.
