https support (silightly different approach)

[Norbert Kiesel <nkiesel@...>]

Hi,

I just subscribed so I can't continue the thread "Q: luasocket https
client?" started on 2009-02-13.  I faced the same problem some time back
(actually for allowing HTTPS SOAP calls), but I added an optional
parameter to socket.http.open:

function open(host, port, create, security_context)
    -- create socket with user connect function, or with default
    local c = socket.try((create or socket.tcp)())
    local h = base.setmetatable({ c = c }, metat)
    -- create finalized try
    h.try = socket.newtry(function() h:close() end)
    -- set timeout before connecting
    h.try(c:settimeout(TIMEOUT))
    h.try(c:connect(host, port or PORT))
    if security_context then
       h.c = h.try(ssl.wrap(c, security_context))
       h.try(h.c:dohandshake())
    end
    -- here everything worked
    return h
end

security_context id the normal context passed to ssl.wrap

This way I can make both HTTP and HTTPS calls.
