Clients blocked by persistent actions now receive a 403 Forbidden response
TL;DR
Previously, clients that were blocked due to persistent actions received no clear feedback, leading to confusion. Vercel has implemented a 403 Forbidden response for these clients, clearly indicating that access is denied.
✦ Why It Matters
Engineers can enhance user experience by implementing clear feedback mechanisms for access control issues.
Key Takeaways
- Update your application to handle 403 responses from Vercel WAF.
- Monitor client behavior to identify potential persistent actions.
- Optimize your application to reduce edge request load.
- Enhance security measures based on WAF feedback.
How It Works
The Vercel WAF identifies persistent actions, which are repeated requests that may signify malicious intent. When such actions are detected, the WAF now responds with a 403 Forbidden status, clearly indicating that the client's access is intentionally blocked.
This mechanism helps developers understand the nature of the block and take appropriate actions.
