Supports Apache 2.2 proxy

[kenjiuno]

If I use Apache 2.2 proxy, System.Exception: protocol error: more data has been received occurs.

using SuperSocket.ClientEngine.Proxy;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp20
{
    class Program
    {
        static void Main(string[] args)
        {
            var proxy = new HttpConnectProxy(
                new IPEndPoint(IPAddress.Parse("PROXYSERVER"), 55555),
                10000,
                null
                );
            proxy.Completed += Proxy_Completed;
            proxy.Connect(
                new System.Net.DnsEndPoint("ws-mt1.pusher.com", 443)
            );
            Console.ReadLine();
        }

        private static void Proxy_Completed(object sender, SuperSocket.ClientEngine.ProxyEventArgs e)
        {
            Console.WriteLine(e.Connected + " " + e.Exception);
        }
    }
}

Output:

False System.Exception: protocol error: more data has been received

Output with fix-92 (#100) merged.

False System.Exception: protocol error: invalid protocol

I have observed TCP packets communication between ConsoleApp20 and Apache 2.2, where are captured with Wireshark.

Send to proxy:

CONNECT ws-mt1.pusher.com:443 HTTP/1.1
Host: ws-mt1.pusher.com:443
Proxy-Connection: Keep-Alive

Received from proxy:

HTTP/1.0 200 Connection Established
Proxy-agent: Apache/2.2.29 (Win32)
