Dear Guilers,

I'd like to implement a web server using the (web server) module, but
allow for “streaming” results.  The way I imagine this would look like,
is something like this:

(define (request-handler request body)
  (values '((content-type . (text/plain)))
          ;; This function can build its response by writing to
          ;; ‘port’, rather than to return the whole body as a
          ;; string.
          (lambda (port)
            (format port "Hello world!"))))

(run-server request-handler)

Is this possible with the (web server) module?  If so, how?

What you describe is exactly how it works. The second value can
be a bytevector, #f or a procedure that takes a port as argument.

Here is an example use [0] and here is the code [1]

[0] [1]
