What is HTTP 300 Multiple Choices?

HTTP 300 Multiple Choices indicates that the request has more than one possible response. The server is informing the client that there are multiple options available for the requested resource, and the user or user agent should choose one of them.

This status code is rarely used in practice. When implemented, the server should include a list of resource characteristics and locations from which the user or user agent can choose the most appropriate one.

When Does This Happen?

A 300 Multiple Choices response is returned when:

A resource is available in multiple formats (e.g., different languages, file formats)
Multiple versions of a resource exist and the server wants the client to choose
The server cannot determine which representation to return based on the request headers
Content negotiation requires explicit user selection

Common Use Cases

🌐 Content Negotiation Testing

Test how your application handles multiple resource options and content negotiation scenarios.

🔄 Multi-Format Resources

Mock responses for resources available in multiple formats (JSON, XML, etc.) or languages.

📋 Version Selection

Test client behavior when multiple versions of an API or resource are available.

🎯 Client Choice Testing

Verify that your application properly handles scenarios where user selection is required.
