            We are using HttpClient to connect with WebAPI.

            Previously we had used HTTP with localhost, and we were facing 21 secs delay issue randomly.

            We found that it's happened due to proxy settings and we set UseProxy=false in the HttpClientHandler and then 21 secs delay issue was resolved. it was working good so for.

            Actually the web api used the address as IPAddress.Any, instead we changed to particular IP then it's resolved.

            If you just post singal request.there's even no difference between injecting an instance of httpclient and creating a instance of httpclient with httpclientfactory .

            if you use serval instance of httpclient or reuse httpclient to post mutiple requests,some problems may occor,using httpclient could handle these problems. You could create httpclients with differenet settings as follow:

            1. Will it use HttpClientFactory to create an instance of HttpClient?

            Yes. A default HttpClient is registered as a transient service during HttpClientFactory registration.

            1. I guess it uses HttpClientFactory but will it have issues with DNS changes in that case?

            Correct, it still would. As you inject it into a singleton, HttpClient here will be created only once. In order to make use of HttpClientFactory's HttpMessageHandler pooling, you'd need your HttpClients to be short-lived. So, for this you would rather need to inject IHttpClientFactory itself and call CreateClient when you need one. (Note that short-living HttpClients only apply to HttpClientFactory usage). BTW switching to a typed client will not help when injecting into a singleton, HttpClient will still end up being created only once, see https://github.com/dotnet/runtime/issues/64034.

            Also, you can actually avoid HttpClientFactory entirely and still have DNS changes respected. For that you may have a static/singleton HttpClient with PooledConnectionLifetime set to some reasonable timeout (e.g. the same 2 minutes HttpClientFactory does)

            No response when request takes 5 minutes or longer
            Asked 2022-Jan-30 at 18:36

            I have encountered a very strange issue - HttpClient's SendAsync never returns when request to the specific web server takes 5 minutes or longer.

            ...

            ANSWER

            Answered 2022-Jan-30 at 18:36

            I would really recommend that you not execute a five minute delay in your API controller. It will give you more grief than it's worth. For example, when IIS restarts your AppPool, it will wait up to 90 seconds for requests to process. During these autonomous restarts, this request will be aborted.

            The problem server may have TCP KeepAlive set to Microsoft's recommended (but not default) value of 5 minutes. Because the HttpClient doesn't implement TCP keepalives by default, the problem server OS is likely disconnecting the TCP socket before the response is sent to the client because the client fails to respond to the keepalive being sent by the problem server OS.

            You could adjust the TCP KeepAlive setting at the OS level on the problem server by editing the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\ subkey as described here.

            Alternatively, you can configure the client to support TCP keepalive before sending the request by configuring the ServicePoint. If there is a network device, such as a stateful firewall, between the client and server, a high frequency keep-alive setting may help keep the connection open.

            When making an instance of the OrderLine type, you're using the Object Initializer syntax. However, because you explicitly made a Constructor with non-zero arguments, you must call that first.

            HttpGet IActionResult method calling microservice returns all attributes as null
            Asked 2021-Dec-24 at 07:09

            I'm following this tutorial and specifically using the code from the Basic Usage section.

            When I send a GET request from Postman to http://localhost:9000/api/gateway, I get the right number of objects, as many as are in the database, but all attributes as null.

            I tried changing the ReadAsStreamAsync to ReadAsStringAsync, and I actually got one big string, an array of all the records from the database.

            The attributes were NOT null there, but I don't know how to parse a string into an IEnumerable of objects, so that doesn't help me much.

            Anybody have an idea what I could be missing? See the controller method below.

            Note that the method sends HTTP requests to localhost:5000, but the method itself receives incoming requests on localhost:9000.

            The goal is to create an API Gateway, that calls another microservice and is not supposed to have a direct access to the database of the microservice it is calling.
