I had to implement HTTP/1.1 for the Palm for my application, so here are a
couple differences I noticed between your code and mine:
In the NetLibSocketOpen, I just use "0" or null for flags parameter (you
have netSocketProtoIPTCP); I don't know if that matters.
More importantly, your "(NetSocketAddrType *) &sockAddrP, &sockAddrPlenMine
" parameters might be causing trouble in your NetLibReceive call. I
dutifully supplied these parameters at first, but then found that they're
unnecessary for TCP, and in fact cause the call to puke. After passing
nulls (or zero), it worked fine.

Subject: Re: Problems sending an HTTP header to a Web Server
Hi again,
Thanks for what you told me, I have changed what I have leaving only the
two
new lines, but I still have the other problem, I get nothing from the
server.
I am sending a piece of code where I make the sending and receive part,
maybe I have something that shouldn�t been there.
Thanks for all the help.
// Open the socket
timeout = (UInt32)SysTicksPerSecond() * 20;
SocketRef = NetLibSocketOpen (NetLibNum, netSocketAddrINET,
netSocketTypeStream, netSocketProtoIPTCP, timeout, &errors);
// Resolve the FIXED ADDRESS
sockAddrP.family = netSocketAddrINET;
sockAddrP.port = NetHToNS(80);
IPAddr = NetLibAddrAToIN (NetLibNum, "172.19.1.48");
MemMove ((Char*)&sockAddrP.addr, (Char*)&IPAddr, sizeof(IPAddr));
// Make the connection
timeout = (UInt32)SysTicksPerSecond() * 20;
ConnectResult = NetLibSocketConnect (NetLibNum, SocketRef,
(NetSocketAddrType*) &sockAddrP, sizeof(sockAddrP) ,timeout,
&errors );
// Send data
timeout = (UInt32)SysTicksPerSecond() * 20;
lenbuffer = StrLen(buffer);
sockAddrPLen = sizeof(sockAddrP);
bytesSent = NetLibSend(NetLibNum, SocketRef, buffer, StrLen(buffer),
netIOFlagOutOfBand,
(NetSocketAddrType *) &sockAddrP, sockAddrPLen, timeout, &err);
bytesReceived = NetLibReceive(NetLibNum, SocketRef, &bufferIN[index],
RECV_BUFFER-index, 0,
(NetSocketAddrType *) &sockAddrP, &sockAddrPlenMine, timeout, &err);
As soon as I do this last call, I get a -1 in bytesReceived an nothing in
bufferIN.
