POST request
JLM
I am trying to simply use the function Data = Req:parse_post(), in my
app but the server never respond until 300 seconds.
It seems that it's waiting for something.
My HTTP Client is a firefox add-on called "REST Client" on which I've
configured a POST request with a request Boyd to an URL served by my
mochiweb application (GET requests work fine).
Mochiweb version : retrieved from master branch on github on the

Got the same behavior, the request stays hanged in the recv method of mochiweb_request

I've started a blank application with mochiweb and POST requests work
just fine.
In fact, my application is based on the articles by Richard Jones
about a 1-Million user comet application.
In one of the comments, someone provided a way to detect for client
disconnections by adding the following lines at the beginning of the
loop function :
Socket = Req:get(socket),
inet:setopts(Socket, [{active, once}]),
And this is what spoiled the behavior of POST requests.
Maybe is there a better way to manage client disconnections on long
running requests ?

quick way to fail.
Detecting disconnections is not really necessary, the process will
terminate when that happens... but only while you're waiting on
activity from the socket, such as parsing the request body or waiting
for the next request. Richard's method should only be useful if you're
long-polling and you want to detect a disconnect from the client
before you send the response.

I've found my mistake by starting from a new sample app and it works
perfectly. It's absolutely not Mochiweb's fault.
I've used a sample code on an article by Richard Jones about a one-
million users Comet Application.
In comments, someone provided a way to detect for disconnections by
configuring Socket :
Socket = Req:get(socket),
inet:setopts(Socket, [{active, once}]),
This is the reason why POST requests never ended.
So I've moved this code in the GET request case I used for the Comet
behavior.
Maybe would you have a better way to detect when a client
disconnects ?
