The http.server.responses vocabulary provides constructors for a few useful response objects.

For successful responses:

<content> ( body content-type -- response )

<text-content> ( body -- response )

<html-content> ( body -- response )

For errors:

<304> ( -- response )

<403> ( -- response )

<400> ( -- response )

<404> ( -- response )

The http.server.responses already provides many more canned responses. New error responses like the above can be created for other error codes too:

<trivial-response> ( code message -- response )
