Hi
Yes that may work for you now.
But core solution will need to be "a bit" more complex to support
more flexible configuration and per service.

Subject: Re: [Opensim-dev] Question about https login authentication
Thank you for your response,
Currently, I am interested only in secure connection in the login
authentication, so https is needed in robust, in my case, and not in
regions, nor other services.
I have to do more tests, but it seems that only minor changes are needed
in function "public static IHttpServer GetHttpServer(uint port, IPAddress
ipaddr)" of file "MainServer.cs" (modifications respect original source are
inside block "scc"):
_________________________________________
/// <summary>
/// Get the default http server, an http server for a specific
port
/// and/or an http server bound to a specific address
/// </summary>
/// <remarks>
/// If the requested HTTP server doesn't already exist then a new
one is instantiated and started.
/// </remarks>
/// <returns></returns>
/// <param name='port'>If 0 then the default HTTP server is
returned.</param>
/// <param name='ipaddr'>A specific IP address to bind to. If
null then the default IP address is used.</param>
public static IHttpServer GetHttpServer(uint port, IPAddress
ipaddr)
{
if (port == 0)
return Instance;
if (instance != null && port == Instance.Port)
return Instance;
lock (m_Servers)
{
if (m_Servers.ContainsKey(port))
return m_Servers[port];
////////////////// scc
//IConfigSource defaultConfig = new IniConfigSource();
//IConfig networkConfig =
defaultConfig.Configs["Network"];
bool ssl_main = networkConfig.GetString("ssl_main",
String.Empty);
string cert_path = networkConfig.GetString("cert_path",
String.Empty);
string cert_pass = networkConfig.GetString("cert_pass",
String.Empty);
if (!ssl_main)
m_Servers[port] = new BaseHttpServer(port);
else
{
if (cert_path == String.Empty)
{
System.Console.WriteLine("ERROR: Path to X509
certificate is missing, server can't start.");
Environment.Exit(1);
}
if (cert_pass == String.Empty)
{
System.Console.WriteLine("ERROR: Password for X509
certificate is missing, server can't start.");
Environment.Exit(1);
}
m_Servers[port] = new BaseHttpServer(port, ssl_main,
cert_path, cert_pass);
}
////////////////// scc
if (ipaddr != null)
m_Servers[port].ListenIPAddress = ipaddr;
m_Servers[port].Start();
return m_Servers[port];
}
}
