The CMS hosting doesn’t allow static page hosting. That is I can’t have http://www.foo.com/something serve a json or text file.
Our DNS has a CNAME for www to proxy-ssl dot webflow dot com. So I deleted that and pointed an A record for www to my server’s ip.
I setup a reverse proxy in golang to that same proxy-ssl.webflow.com address and use it for everything except that one static file. But it doesn’t work. Every hit thru the proxy is a 404 this way.
Custom reverse proxies can be difficult to configure and maintain. I’ve set up several proxies for Webflow sites in my time, and every site usually has slightly different requirements.
