Thanks Badlop, I've looked at

Thanks Badlop, I've looked at yaws but I wasn't aware of that kind of integration with ejabberd, I'll definitively look at it. These are simple questions but I'm still a beginner with ejabberd (and erlang as well..)

Well, if you found that

Well, if you found that ejabberd's listener is slowing you, you can avoid it. In the same Erlang node where ejabberd is running, you can start other applications, Yaws for instance, and serve HTTP queries from there. See https://www.ejabberd.im/yawspack for example

It's related to Erlang (I'm a pool imperative programmer sorry :) ), you're right, but I'd like to explain you why ejabberd matters.
In these days I have spent some time on it and I figured out how to avoid this problem with gen_tcp. I have seen yaws and other projects and those pointed me on serving http content as multipart/form data. I have built something from scratch without ejabberd and I have had quite good results, now the problem seems to be related to process/2 in my module, I'm under ejabberd_http in my config file, something like:

-
  port: 5280
    module: ejabberd_http
    request_handlers:
      "/files": modfileupload  ## Here I am
    http_bind: true
    register: false
    captcha: false

and when something like http://localhost:5280/files/somethingelse is called I receive a request on process/2. process/2 needs to return back some data with a tuple like {HTTPCode, Headers, PageContent}. If PageContent is huge everything crashes.
I wish to reply back to the client directly (on a socket) without passing the content inside a tuple/variable to someone else function. I'd like to manage directly the headers and output data as multipart to the client, I guess I could obtain better results. It seems ejabberd_http.erl calls socket_handoff/6 in my module (when available) but I don't know how to use it or if there're usage examples.
Any hints ? Am I following the right path ?

Thanks again
Ben

Your problem is more related

Your problem is more related to the erlang language, and the OTP libraries than ejabberd. Look at HTTP servers written in erlang, starting with Yaws, maybe they give you some hint?
