persistent HTTP connection using cohttp library (or other)

It seems (based on wireshark), cohttp client closes its connection automatically after response to GET request was received.
Is there a way to keep this connection alive (to make it persistent)?
If no is there any other HTTP library to create persistent connections?

Looking at the code at github it doesn't look like there is such an option.

let call ?(ctx=default_ctx) ?headers ?(body=`Empty) ?chunked meth uri =
  ...
  Net.connect_uri ~ctx uri >>= fun (conn, ic, oc) ->
  let closefn () = Net.close ic oc in
  ...
  read_response ~closefn ic oc meth

Where read_response is:

let read_response ~closefn ic oc meth =
  ...
   match has_body with
    | `Yes | `Unknown ->
      let reader = Response.make_body_reader res ic in
      let stream = Body.create_stream Response.read_body_chunk reader in
      let closefn = closefn in
      Lwt_stream.on_terminate stream closefn;
      let gcfn st = closefn () in
      Gc.finalise gcfn stream;
      let body = Body.of_stream stream in
      return (res, body)

If I am reading this correctly the connection will close as soon as the GC cleans up the stream.
