Hi everyone,

I have just discovered a strange behavior of ocamlnet.

As i understood, it seems like if you load certain library together, the
library is unable to make a simple http_get.
I need to add these libs (particularly SSL), because i have to write a POST
multipart https function.

Here an example with the toplevel which show the problem :
(Sorry for the long long command)

1. It works :-)

$ ocaml -I /opt/local/lib/ocaml/site-lib/pcre -I
/opt/local/lib/ocaml/site-lib/netsys -I
/opt/local/lib/ocaml/site-lib/netstring -I
/opt/local/lib/ocaml/site-lib/netcgi2 -I
/opt/local/lib/ocaml/site-lib/equeue -I

        Objective Caml version 3.12.1

# Http_client.Convenience.http_get "http://perdu.com";;
- : string =
"<html><head><title>Vous Etes Perdu ?</title></head><body><h1>Perdu sur
l'Internet ?</h1><h2>Pas de panique, on va vous aider</h2><strong><pre>
* <----- vous &ecirc;tes ici</pre></strong></body></html>\n"

Objective Caml version 3.12.1

# Http_client.Convenience.http_get "http://perdu.com";;
Exception:
Http_client.Http_protocol (Unix.Unix_error (Unix.EINPROGRESS, "connect",
"")).


So every http_call doesn't work, and of course https  with post verb.

is anayone have an idea ?



Merry Christmas to all !
