Can I upload from Spinneret to a remote server?

I don't understand your two web server set up or what you're looking for.

Check out my budding tutorial and see if that helps.

I'm using the Spinneret more like a client, I guess. It only needs to send and receive data from another website. None of the webpage is being served up from the spinneret. How could I have the Spinneret sending a request to my website on one socket, and then receiving a response from the same website on another? I wish I had some code to give you to look at...but I don't understand the W5100 Driver enough to write any code.

I also need to parse the data coming into the spinneret to get the specific data I want. How would I go about doing that. I think it would help me more if I had a ground up explanation...instead of trying to do it through your written code...because that doesn't seem to work very well for me.

That's not how HTTP works. Open a socket -> send a request -> receive a response => close the socket. I think you want two ports; one socket on port 5000 and another on 5001.

I also need to parse the data coming into the spinneret to get the specific data I want. How would I go about doing that.

The string methods object has a MatchPattern method. You could use that... it's the work horse of the entire Multi-Socket server. Moreover, I think you need to study the HTTP protocol, the Propeller manual, and the W5100 manual. Everything you're asking is available in the examples provided.

When I get home from work I'll try to whip something up as an example.

Ok work has been nuts but here's your example.

1) Add a port2 and set the tcpMask member in the DAT section

DAT
  port2                 word    5010 
...
  tcpMask               byte    %0111
  udpMask               byte    %0000  

2) Initialize the sockets to use IDs 0 to 2

  ' Initailize TCP sockets (defalut setting; TCP, Port, remote ip and remote port)
  repeat id from 0 to 2
    InitializeSocket(id)
    Request.Release(id)
    pause(50)

  ' Set all TCP sockets to listen
  pst.char(13) 
  repeat id from 0 to 2 
    Socket.Listen(id)
    pst.str(string("TCP Socket Listener ID   : "))
    pst.dec(id)
    pst.char(13)
    pause(50)

3) Execute your server request.

PUB Main | packetSize, id, i, reset, j, temp
  ''HTTP Service

  GetMyIp(3)

The method that makes the call

PUB GetMyIp(id) | st, size, idx, tempMask

  InitializeSocket2(id)
  pause(delay)

  'Get My IP
  pst.str(string(13, "Getting Assigned IP ",13))
  Socket.Connect(id)
  pause(delay)
  repeat while !Socket.Connected(id)


  pst.str(string(13, "Connected Sending Header ",13))

  'Header
  StringSend(id, string("GET /spinneret/myip.aspx HTTP/1.1", 13, 10))
  StringSend(id, string("Keep-Alive: 115", 13, 10))
  StringSend(id, string("Host: agaverobotics.com", 13, 10))
  StringSend(id, string("Connection: keep-alive", 13, 10, 13, 10))


  pst.str(string(13, "Waiting for response ",13))

  'Wait for response
  repeat until size := Socket.rxTCP(id, @rxdata)

  'Find and print the message body
  idx := str.MatchPattern(@rxdata, string(13,10,13,10), 0, true)
  pst.str(@rxdata+idx+4)

  'Reset the socket
  Socket.Disconnect(id)

  return

PRI InitializeSocket2(id)
  Socket.Initialize(id, TCP_PROTOCOL, port2, remotePort, @remoteIp)
  return

This will hit my web site and return your IP as a string.

Socket 3 is on it's own port. Every time GetMyIp(id) is invoked the connection to the server is initialized, communication happens, and the socket is disconnected. Parsing the response or request is up to you.
