Adding Custom SocketsHttpHandler Support

[KFKMan]

Hi, i have a 2 type HttpClient.
1 => Default
2 => With custom SocketsHttpHandler

i want to add support for my custom SocketsHttpHandler.

How can i add that?
Can i override default?
Can i add support without override default one (supporting both in same time)? And how can i do that? With using another port, prefix route... etc?
How can i get custom data which is getted from SocketsHttpHandler?

You can use the HttpClientFactory in ASP.NET Core to register and manage multiple HttpClient configurations. This allows you to use different handlers for different clients without overriding the default one.

public void ConfigureServices(IServiceCollection services)
{
    // Register default HttpClient
    services.AddHttpClient("default");

    // Register custom HttpClient with custom handler
    services.AddHttpClient("customClient");
}

Then in your code use the custom instance:

public class YourService
{
    private readonly HttpClient _defaultClient;
    private readonly HttpClient _customClient;

    public YourService(IHttpClientFactory httpClientFactory)
    {
        _defaultClient = httpClientFactory.CreateClient("default");
        _customClient = httpClientFactory.CreateClient("customClient");
    }

    public async Task UseClientsAsync()
    {
        var responseDefault = await _defaultClient.GetAsync("https://something");
        var responseCustom = await _customClient.GetAsync("https://something");
       // ....
    }
}

Anyway, if you want to override the default:

var customHandler = new SocketsHttpHandler
{
    // Custom settings here
};

// Create a single HttpClient instance with the custom handler
var httpClient = new HttpClient(customHandler);

var response = await httpClient.GetAsync("https://something");
