Proxy protection on sub-domains managed through Netlify

[luke]

Hi, @maggie0002. If you were doing this with Netlify DNS, the solution to proxy to another service from our CDN would work like this:

1. Create a site at Netlify.
2. Add the domain names to the site under Site Name > Settings > Domain management > Custom domains.
3. Write proxy redirect rules for the site for those domain names.

Note, using Netlify DNS isn’t required. You can also use third-party DNS (like Cloudflare’s DNS). If you do move to Cloudflare for DNS, you can still host the sites at Netlify using that domain but there are important considerations which are covered in the support guide below:

[Support Guide] What problems could occur when using Cloudflare in front of Netlify?

Last reviewed by Netlify Support - August, 2023 Note: We recommend not using both Cloudflare’s CDN (“Accelerate and Protect”, the orange cloud in their UI) and Netlify for the same site at the same time. Why? Read on! Netlify’s web service is not designed to work optimally with another CDN “in front of” our CDN. Proxying to our service is in general not supported and we advise you not to do it for best hosting results. Cloudflare has made similar statements that it doesn’t recommend this usa…

To summarize, you must either not proxy for the domains hosted at Netlify (but you could proxy for sites hosted outside of Netlify which were using subdomains of that domain) or bring your own SSL certificate if you decide to use their proxy feature.

If there are other questions about this, please let us know.
