Default implementation... others can override to do this much faster
int size = 0;
InputStream in = null;
try {
in = getInputStream();
int read = 0;
byte[] data = new byte[1024];
while ((read = in.read(data)) > 0) {
size += read;
}
} finally {
try {
if (in != null) {
in.close();
}
} catch (IOException ioe) {

// unavailable
}
}
return size;
