Info Risk
📖 What Is HTTP 303?
The response to the request can be found at another URL using GET. Typically used after a POST to redirect to a confirmation or result page.
🛡️ Security Implications
Low risk. Standard Post-Redirect-Get (PRG) pattern to prevent form resubmission on browser refresh.
🔍 Common Causes
After processing a form submission, the server redirects to a result page to prevent duplicate submissions.
🔧 How to Fix
No fix needed. This is the correct pattern for form processing. Ensure the redirect URL is not user-controlled.
