ConcurrentRequests

object ConcurrentRequests

Middlewares for tracking the quantity of concurrent requests.

These are generalized middlewares and can be used to implement metrics, logging, max concurrent requests, etc.

Source
ConcurrentRequests.scala
Note

The concurrent request count is decremented on the completion of the Response body, or in the event of any error, and is guaranteed to only occur once.

    Run a side effect each time the concurrent request count increments and decrements.

    Each side effect is given the current number of concurrent requests as an argument.

    onIncrement should never be < 1 and onDecrement should never be value < 0.
