appendedLen  = "2687868";
int lengthToCheck= inFromClient.read(ch, 0, ch.length);  

while (appendedLen >= lengthToCheck) {
    request = request + String.valueOf(ch).trim();

    if ((appendedLen - lengthToCheck) != 0) {
        ch = new char[appendedLen - actualLen];
        actualLen = inFromClient.read(ch, 0, ch.length);

        lengthToCheck = lengthToCheck + actualLen;
