Websocket and SSL on many ports

[olleharstedt]

Hello

I'm using your library for my card playing webpage (thanks for that)! Now I try to switch to SSL, but the websocket will no longer connect (I've also switched from "ws://..." to "wss://..."). This is the error I receive:

Lwt_stream.Empty[Thu Jun 27 12:44:44 2013] [OcamlNet] /cgi-bin/drakskatten_ajax: Netchannels.Closed_channel (Status 500), referer: https://127.0.1.2/cgi-bin/drakskatten

I'm using the cgi app as a small websocket server, where each instance listens on a unique port, starting from 8080.

Do you know what's going on? Is it apache? Or should I use the Lwt_ssl socket type instead of the regular?

Loading webpages from the cgi works properly, even with SSL. Websocket works without SSL, but not with.

Grateful for your help
Olle

I’m going to have a look tomorrow.
Thanks for your interest in the library :)

Oh, I thought it was MY websocket library. Sorry :)

[olleharstedt]

Ah, no, not ocaml-websocket, but lwt-websocket. :)

Do you know how to use websockets with SSL? Just switching to "wss://..." doesn't seem enough. This is the setup code I use. Should I use another socket type to get it to work with SSL?

   let start_websocket env = 
     let addr_inet = Unix.ADDR_INET (Unix.inet_addr_of_string env#addr, env#port) in 
     let sock_listen = Lwt_unix.socket Unix.PF_INET Unix.SOCK_STREAM 0 in 

     (** setup listen socket *) 
     Lwt_unix.setsockopt sock_listen Unix.SO_REUSEADDR true; 
     Lwt_unix.bind sock_listen addr_inet; 
     Lwt_unix.listen sock_listen 5; 
     ...

Apache2 takes care of the SSL, so I'm at bit of a lost, here.

It is yours. Not sure where the fault is, though. Do you know how to use websockets with SSL? Just switching to"wss://..." doesn't seem enough.

Ok, you're talking about my fork of this library then. I wrote another
websocket library completely from scratch (ocaml-websocket) that I hope
is working over SSL (not even sure…). I never used this library
actually, I might have a look in some time but I'm currently too busy.

Good luck,

Vincent
