[racket] launching DrRacket from a web browser

I'd like to set up a web site with links that cause the server to
deliver Racket source code.  Receiving such could would cause the web
server to launch DrRacket.  I believe the right mechanism to use here
is a MIME type ('Content-Type:' header in the HTTP protocol).

My question is whether there is an existing MIME type used for
describing Racket source files and if installing the Racket system
tells local web browsers about this type---or if I will have to figure
out for myself how to configure this behavior?
