I installed the Timeout feature of the Ktor HttpClient, because I have some specific request that might take a long time, so I installed the feature:
Copy code
httpClient = HttpClient(CIO) {
        install(HttpTimeout) {
            requestTimeoutMillis = 60000
        }
        engine {
            maxConnectionsCount = 10000 
            endpoint.apply {
                maxConnectionsPerRoute = 1000 
                pipelineMaxSize = 100
                keepAliveTime = 5000 
                connectTimeout = 5000 
                connectRetryAttempts = 3
            }
        }
}
and in my request, I specifically overwrite the requestTimeout:
Copy code
<http://httpClient.post|httpClient.post><MyResponse> {
                    url(myUrl)
                    contentType(ContentType.Application.Json)
                    timeout {
                        requestTimeoutMillis = TimeUnit.MINUTES.toMillis(30)
                    }
                    body = myBody
}
But I still got a coroutine
TimeoutCancellationException
after 15 seconds. I then specified the engine.endpoint.requestTimeout to be longer and the Exception went away - so am I not able to overwrite the CIO engines timeout with the Timeout feature? By the Timeout feature documentation, a
HttpRequestTimeoutException
should be thrown, not a Coroutine timeout exception, so it appears to get ignored. Can I overwrite the request timeout for CIO for a specific request? Or should I increase the CIO timeout a lot and then use the HttpTimeout feature to reduce it again?

@maxmello did you ever figure this out?

@Evan I did what is wrote in the last sentence, the CIO default request timeout is high and I reduce it per request with the timeout { … } block.
