Exception handling is required in any application. It is a very interesing issue where different apps have their own various way(s) to handle that. I plan to write a series of articles to discuss this issue

This article is information collection for HttpStatusCode.

The HttpStatusCode is used in ASP.NET Web API:

HTTP response status codes

HTTP response status codes indicate whether a specific HTTP request has been successfully completed. Responses are grouped in five classes:

  1. Informational responses (100 – 199)
  2. Successful responses (200 – 299)
  3. Redirection messages (300 – 399)
  4. Client error responses (400 – 499)
  5. Server error responses (500 – 599)

The status codes listed below are defined by RFC 9110.
