The docs for available states that it’s “*an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream*“, so that should be expected.
Assuming your servlet is async, you should probably call something like setReadListener(ReadListener). If not async, you should probably not check available, since it’s not going to tell you anything useful anyway.
