Is it possible to limit the transfer size in a correct way?

[Speedkore]

i had to modify the source code in my way to limit big transfers, how could i do it in a right way?
i never receive fragment packets or anything, if i send for example a file of 100MB it is done in one step by Socket.Web.recv() in memory

this is what i did, in file web.ex, line 577:

@SPEC recv(t, boolean, non_neg_integer, Keyword.t) :: { :ok, binary } | { :error, error }
defp recv(%W{socket: socket, version: 13}, mask, length, options) do
length = cond do
length == 127 ->
case socket |> Socket.Stream.recv(8, options) do
{ :ok, << length :: 64 >> } ->
if length > 5_000_000 do
{:error, :transfer_too_large}
else
length
end

[meh]

The server/client should fragment the packets.

I'm doing this to avoid a malicious attack from the client side that eats all the memory of the server, sending a large bunch of data. How do i tell the server to fragment packets when receiving them? or it's just enough what i did to avoid this kind of attack?

Thanks a lot for the response , you made a great library and it works very well!!
