# How to add additional headers if reverse proxy isn't supported on public bucket?

❓Question

Hi! I have a public bucket and I want to add custom headers on its content like content-security-policy and permissions-policy. But enabling the proxy mode on Cloudflare CDN breaks the certificate renewal  How to go about it?

## Solution

Hi! Unfortunately, we don't support this functionality yet. Additional headers on the Tigris side are limited to X-Content-Type-Options: nosniff ([https://www.tigrisdata.com/docs/buckets/settings/#additional-headers](/content/docs/buckets/settings/#additional-headers/index.html)), and Cloudflare's CDN (in proxy mode) breaks certificate renewal. At this point, we don't have a way to work around this. We'll let you know when that changes.

### Tigris Dashboard

The Tigris Dashboard lets you configure various settings for your buckets.

### Continuation

Aww, alright. I hope we get this feature soon!
