BaseHTTPRequestHandler.send_error

http.server

method of BaseHTTPRequestHandler (source) not WASI

BaseHTTPRequestHandler.send_error(code, message=None, explain=None)

Send and log an error reply.

Arguments are
* code:    an HTTP error code
           3 digits
* message: a simple optional 1 line reason phrase.
           *( HTAB / SP / VCHAR / %x80-FF )
           defaults to short entry matching the response code
* explain: a detailed message defaults to the long entry
           matching the response code.

This sends an error response (so it must be called before any
output has been generated), logs the error, and finally sends
a piece of HTML explaining the error to the user.
