What is the difference between Ihttp and Http?

Question

Its an interview question Please help me out for this

The difference between IHttp and Http can be understood in the context of the .NET framework specifically within the realm of HTTP services and clients in ASP.NET applications. IHttp Interface : IHttp is generally used to refer to an interface in the .NET framework. An interface defines a contract that classes can implement. In the context of HTTP communication interfaces are used to define methods for making HTTP requests and handling responses. Dependency Injection : Interfaces like IHttp are often used in dependency injection to decouple the implementation of HTTP communication from the code that relies on it. This makes the code more modular testable and maintainable. Custom Implementations : By using an interface like IHttp  developers can create custom implementations of HTTP clients which can be especially useful for unit testing or when different implementations are needed for different environments. Example : A custom interface might look like this: public interface IHttp { Task GetAsync(string requestUri); Task PostAsync(string requestUri HttpContent content); } Http Concrete Class : Http typically refers to a concrete class provided by the .NET framework for handling HTTP requests and responses. The most commonly used concrete class for HTTP communication in .NET is HttpClient . Functionality : HttpClient provides a high-level API for sending HTTP requests and receiving HTTP responses from a resource identified by a URI. It supports various HTTP methods such as GET POST PUT DELETE etc. Usage : HttpClient is used directly to perform HTTP operations. It provides built-in methods for making asynchronous HTTP requests and is highly configurable supporting features like request headers timeout settings and automatic handling of cookies. using System.Net.Http; using System.Threading.Tasks; public class MyHttpClient { private readonly HttpClient _httpClient; public MyHttpClient(HttpClient httpClient) { _httpClient = httpClient; } public async Task GetContentAsync(string url) { var response = await _httpClient.GetAsync(url); response.EnsureSuccessStatusCode(); return await response.Content.ReadAsStringAsync(); } } IHttp is an interface providing a contract for HTTP operations that can be implemented by various classes promoting flexibility and testability. Http (often referring to HttpClient ) is a concrete class provided by the .NET framework used directly to make HTTP requests and handle responses. In an interview context understanding the use of interfaces for dependency injection and the concrete implementations for actual HTTP communication is crucial. This distinction highlights the importance of design patterns and best practices in software development.

In .NET IHttp is not a standard interface or class provided by the framework. The commonly used interfaces and classes for HTTP client functionality include HttpClient and IHttpClientFactory  as previously mentioned. Could you please confirm if this is the correct question that the interviewer asked? If it's Ihttp it might be a custom interface defined in a specific application or library. I could be mistaken or unaware of such a feature available in .NET.

The difference lies between ASP.NET Web API versions and how they handle responses: Http: This likely refers to the general HttpResponseMessage class. It's a fundamental building block for responses in ASP.NET Web API especially in Web API 1 . It provides granular control over the entire HTTP response including headers status code and content. IHttpActionResult: Introduced in Web API 2  this interface offers a more abstracted way to handle responses. It simplifies code and improves unit testing.
