URL Page Redirects

We just launched our glideapp hosted website and I have several important URLs that clients have/use and also others that show up in google search results and need to create a redirect to the new pages within glideapp.

OLD: www.mydomain.com/this-is-the-url
NEW: www.mydomain.com/dl/this-is-the-url

I can’t get this to work using Cloudflare page rules and was hoping there might be another work around directly within glideapp while I try and figure out why cloudflare isn’t working. I have cloudflare set as “proxied”.

Any thoughts or tricks?
