http_reactor allows one to pull the next request from a connected
client, and to deliver the response to the protocol engine.method next_request : unit -> http_reactive_request option
After receiving the request, one must either call accept_body when the
request is acceptable and one want to reply afer evaluating the body, or
invoke reject_body when the request can be denied without looking at the
body. One must also call accept_body when there is not any body (it
is a no-op then). The HTTP protocol explicitly forbids to perform the request
when reject_body has been invoked ("The origin server MUST NOT
perform the requested method if it returns a final status code").
The response must be written to the Netcgi environment. Depending on
config_reactor_synch the response is immediately transmitted to the
client or at some specified time in the future (untransmitted data is buffered
in this case).
While transmitting output, the reactor is able to read the next request in the background when the limits for the pipeline size allows that.
While receiving input, the reactor is able to write untransmitted response data in the background.
It is an error to call next_request again before the previous request
is completely processed (you can ensure this by calling finish).
In this case the HTTP connection is immediately shut down.
The method next_request returns None when all requests of the
connection are processed.
method close : unit -> unitnext_request returned None. It can also be called at any
time to shut down the connection prematurely (this means a lingering close,
and may cost some time).
