Unity builds by default WebGL using brotli. This is fine, but it seems that no webserver ever knows that it needs to respond with Content-Encoding: br
.
This server does that. It will detect when accessing a .br file and respond with the correct content-type and with the encoding set.
Warning
This code is not for production use. It has very little in terms of security and is only designed to verify builds are working.
