PHP byte serving PDF with fast web view

Question

I have a large PDF file, and host in PHP server.

The PDF is "fast web view" enabled. I want user see the page 1 asap the PDF is start loading.
Refer to the solution from : http://www.coneural.org/florian/papers/04_byteserving.php

I refer to the solution to build a demo.

<?php
include_once('pdfbyteserve.php');
byteserve('pdf/sample_large.pdf');
?>

It is working in Chrome and Firefox, it display the page 1 asap, and continue to load.
But the IE 8 display keep loading and loading, and finally display this error too:

I understand this may the Adobe Reader problem, can I fix it? because most of my user is using IE 8 + Adobe Reader XI.

---

I have no idea what is going on, I am a fool in web development.
anyway I compare the apache log between IE and Chrome.

---

apache access log when IE request the page.

I observed that, both IE and Chrome will get 200 first and then 206.
200 with the total filesize (in my case is about 17MBytes)
then with a series of 206, with the partial size, the partial size pattern is different, why?

---

Now, I just use the netbeans debugger to trace what is going on, when using IE 8, the Adobe Reader error will popup when running this code:

else{
    //no byteserving
    header("Accept-Ranges: bytes");
    header("Content-Length: $filesize");
    header("Content-Type: application/pdf");
    readfile($filename);
}

I still trying to understand what is the problem......

Answer 1

WHAT A FOOL I AM!!!!!

xxxxxxxxx<?php
include_once('pdfbyteserve.php');
byteserve('pdf/sample_large.pdf');
?>

Finally, I discover my demo fail, because my demo code send extra spaces (XXXXXXXX), which corrupt the pdf. I am very sorry and regret I waste a whole day.
