Arduino POST fails to complete - node.js

Question

I am making a post request on an Arduino device with the Ethernet shield. The server is a Node.js server, and I have handled the post request server-side with the same results both with formaline and formidable. The POST is processed, but it doesn't complete the file transfer.
loadstart: {"time":1339574854222}
"bytesReceived": 178,
"filesCompleted": 0
This is the code that sends the post:
String boundary = "--73249889599006000";
String URL = "/upload";
String contentType = "text/plain";
String fileName = "text.txt";
void sendData(){
String thisFile = "This is not the contents of thisFile";
Serial.println("connecting...");
// If you get a connection, report back via serial:
if (client.connect(server, 80)) {
Serial.println("connected");
// Make a HTTP request:
String postHeader = "POST " + URL + " HTTP/1.1\n";
postHeader += "Content-Type: multipart/form-data; boundary=";
postHeader += boundary + "\n";
postHeader += "Host: 192.168.3.78\n";
postHeader += "User-Agent: Arduino\n";
postHeader += "Referer: http://192.168.3.78/upload\n";
String requestHead = "\n--" + boundary + "\n";
requestHead += "Content-Disposition: form-data; name=\"upload\"; filename=\"" + fileName + "\"\n";
requestHead += "Content-Type: " + contentType + "\n\n";
String tail = "\n--" + boundary + "--\n\n";
int contentLength = requestHead.length() + thisFile.length() + tail.length();
postHeader += "Content-Length: " + String(contentLength, DEC) + "\n\n";
char charBuf0[postHeader.length() + 1];
postHeader.toCharArray(charBuf0, postHeader.length() + 1);
client.write(charBuf0);
char charBuf1[requestHead.length() + 1];
postHeader.toCharArray(charBuf1, requestHead.length() + 1);
client.write(charBuf1);
char charBuf2[thisFile.length() + 1];
postHeader.toCharArray(charBuf2, thisFile.length() + 1);
client.write(charBuf2);
char charBuf3[tail.length() + 1];
postHeader.toCharArray(charBuf3, tail.length() + 1);
client.write(charBuf3);
}

Line endings and a few other tweaks sorted it. Here is the updated code that works well with formaline.
String boundary = "--73249889599006000";
String URL = "/upload";
String contentType = "text/plain";
String fileName = "text.txt";
void sendData(){
String thisFile = "This is not the contents of thisFile\r\n\r\n";
Serial.println("connecting...");
// if you get a connection, report back via serial:
if (client.connect(server, 80)) {
Serial.println("connected");
// Make a HTTP request:
String postHeader = "POST " + url + " HTTP/1.1\r\n";
postHeader += "Content-Type: multipart/form-data; boundary=";
postHeader += boundary + "\r\n";
postHeader += "Host: 192.168.3.18\r\n";
postHeader += "User-Agent: Arduino\r\n";
postHeader += "Referer: http://192.168.3.18/upload\r\n";
String requestHead = "--" + boundary + "\r\n";
requestHead += "Content-Disposition: form-data; name=\"upload\"; filename=\"" + fileName + "\"\r\n";
requestHead += "Content-Type: " + contentType + "\r\n\r\n";
String tail = "--" + boundary + "--\r\n\r\n";
int contentLength = requestHead.length() + thisFile.length() + tail.length();
postHeader += "Content-Length: " + String(contentLength, DEC) + "\n\n";
Serial.print("Content-Length: ");
Serial.println(String(contentLength, DEC));
char charBuf0[postHeader.length() + 1];
postHeader.toCharArray(charBuf0, postHeader.length() + 1);
client.write(charBuf0);
Serial.print(charBuf0);
char charBuf1[requestHead.length() + 1];
requestHead.toCharArray(charBuf1, requestHead.length() + 1);
client.write(charBuf1);
char charBuf2[thisFile.length() + 1];
thisFile.toCharArray(charBuf2, thisFile.length() + 1);
client.write(charBuf2);
Serial.print(charBuf2);
char charBuf3[tail.length() + 1];
tail.toCharArray(charBuf3, tail.length() + 1);
client.write(charBuf3);
Serial.print(charBuf3);
}
else {
// kf you didn't get a connection to the server:
Serial.println("connection failed");
}
}
