HTTP status code

The HTTP 300 status code stands for "Multiple Choices". It is a redirection response indicating that the requested resource has multiple representations, and the client (or user) must choose one.

When is HTTP 300 Used?

• When a resource has multiple versions (e.g., different formats, languages, or media types).
• The client may be given a list of available choices to select from.
• The server may or may not include a preferred choice in the response.

Example Scenarios

• Content Format Selection – A document is available in PDF, HTML, and JSON, and the user must choose one.
• Language Selection – A page has versions in English, Spanish, and French.
• Multiple Endpoints – A request could be handled by multiple servers or resources.

Example

Client Request (Requesting a Resource)

  
    GET /document HTTP/1.1
    Host: example.com
  

Server Response (Multiple Choices Available)

  
    HTTP/1.1 300 Multiple Choices
    Content-Type: application/json

    {
      "options": [
        { "url": "/document.pdf", "type": "application/pdf" },
        { "url": "/document.html", "type": "text/html" },
        { "url": "/document.json", "type": "application/json" }
      ]
    }
  

Summary

HTTP 300 means the requested resource has multiple representations, and the client must choose one. It is often used for format selection, language preference, or alternative endpoints.
