Sophos SAV-DI ICAP code sample

Hi everyone,

I was wondering if someone had a working example of using Sophos SAV-DI ICAP protocol to scan a file.

What I have so far is as follows (in C#):

            byte[] buffer = new byte[1024];
            int iRx;
            
            byte[] filestream = ReadFileToArray(@"C:\SophosCLI\testFile.txt");

            string retDesc = String.Empty;
            var soc = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            var remoteEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 1344);

            soc.Connect(remoteEndPoint);

            



            

            if (soc.Connected) {

                Console.WriteLine("Success connecting");

                string cmd = "RESPMOD icap://localhost:1344/AVSCAN?action=SCAN ICAP/1.0\n";
                cmd += "Host: localhost:1344\n";
                cmd += "Preview: 4\n";
                cmd += "Allow: 204\n";
                cmd += "Encapsulated: req-hdr=0, res-hdr=83, res-body=130\n";
                cmd = cmd + "\n";
                cmd += "GET http://localhost/testFile.txt HTTP/1.1\n";
                cmd += "Host: localhost\n\n";
                cmd += "HTTP/1.1 200 OK\n";
                cmd += "Transfer-Encoding: chunked\n";
                cmd += String.Format("{0:X2}", filestream.Length);
                Console.WriteLine(cmd);
                soc.Send(System.Text.Encoding.ASCII.GetBytes(cmd));
                soc.Send(filestream);
                cmd = "\n";
                cmd += "\n";
                cmd += "0\n";
                cmd += "\n";
                Console.WriteLine(cmd);
                soc.Send(System.Text.Encoding.ASCII.GetBytes(cmd));
             


                while ((soc.Connected) && ((iRx = soc.Receive(buffer)) > 0)) {
                    char[] chars = new char[iRx];

                    System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder();
                    int charLen = d.GetChars(buffer, 0, iRx, chars, 0);
                    System.String szData = new System.String(chars);

                    retDesc = retDesc + szData;
                }

            }
            Console.WriteLine(retDesc);

            
            Console.Read();
            Environment.Exit(0);

 As you can see, I am positive that I have many errors especially in my request headers.

If I can see a working example I might have something to work with or a starting point but as you can see from my code above I am lost without it so it'll be so helpful to see something that works. 

What I want to get: I want to be able to either send a file to the sophos engine and get a response OR send a bite array to the sophos engine. I just cant figure out how to attach either.

Any help will be much appreciated!!!
