HTTP 303 See Other — What It Means & How to Fix It

This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: This status code always redirects with a GET request, regardless of the original HTTP method.. It is commonly used in the Post/Redirect/Get (PRG) pattern to prevent form resubmission.. The redirect target is specified in the Location header.. It was introduced in HTTP/1.1 to clarify the behavior of 302.. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

To resolve this, follow these recommended steps: Follow the redirect using a GET request to the Location header URL.. Do not resend the original POST data to the redirect target.. Implement the PRG pattern in your web application to prevent form resubmission issues.. Check that the redirect target page exists and returns the expected content..
