The Vercel platform does not support .htaccess files because our Edge Network does not utilize an Apache HTTP Server.
Using a vercel.json configuration file, the Vercel platform can provide a high level of configuration that is similar to those found in a .htaccess file.
If you cannot find a certain configuration that you wish to use in your Vercel project, please create a discussion in our Vercel Community where members of the community will be able to provide further assistance.
