public virtual signal void got_headers ()
Emitted after receiving all message headers for a message.
(For a client-side message, this is after receiving the Status-Line and response headers; for a server-side message, it is after receiving the Request-Line and request headers.)
If you cancel or requeue
msg while processing this signal, then the current HTTP I/O will be stopped after this signal emission
msg's connection will be closed. (If you need to requeue a message--eg, after handling authentication or
redirection--it is usually better to requeue it from a got_body handler
rather than a got_headers handler, so that the existing HTTP connection can be reused.)
