HTTP 300 Multiple Choices

When is 300 used?

• Content negotiation returning multiple formats
• Mirrors or CDN edge selection

How to handle a 300 response

Follow the Location header. Most HTTP clients do this automatically, and curl -L follows redirects on the command line. Update links and sitemaps that point at permanently redirected URLs.

Check the status code a URL returns from the command line:

curl -s -o /dev/null -w "%{http_code}\n" https://example.com

How to return 300 from your server

Node.js (Express)

res.status(300).json({ message: 'Multiple Choices' });

Python (Flask)

return {"message": "Multiple Choices"}, 300

Go (net/http)
