RTFM about header() and session. There are couple of dozen user
comments about how to set the cache headers correctly in these cases.

("../_JAVARES/car/jammer.jar"); should read 'tj.jar' in 2nd sample.
Sorry :)

Description:
------------
I have a problem trying to redirect a request for a Java .jar through
PHP. I am using PHP 4.3.2 on my Apache test server on Windows, and PHP
4.3.3 on my real Debian webserver. The problem is the same for both
setups.
If I access the .jar directly (no PHP) & use a packet sniffer, I get
returned:
<HTTP headers, Content-Type: text/html >
CRLF CRLF // End of header?
190 CRLF // unknown value
<.jar file>
If I use a simple script with just a readfile, I get returned:
<HTTP headers, Content-Type: text/html >
CRLF CRLF // End of header?
<.jar file>
This request fails to load in any Java VM, which claims the jar is
corrupt. The '190' has mysteriously disappeared.
My real PHP script includes a session to make sure the user is
accessing the jar from our web page only (script appended). This
gives:
<HTTP headers, Content-Type: text/html >
CRLF CRLF // End of header?
2000 CRLF // value now changed!
<.jar file>
This request will work fine with: IE6 & Microsoft VM 1.1, and IE6,
Netscape, Mozilla with Sun VM 1.4+. It does not load correctly if I use
Opera (any VM), or Java 1.3 (any browswer). Changing session cache
controls make no difference.
The main issues are -
What is the '190'?
Why does the plain readfile() not send it?
Why does the session turn it into '2000' which breaks some
browswers?
Thank you for your time,
Dom
Reproduce code:
---------------
<?php
// This fails always
header("Content-Type: text/html; charset=ISO-8859-1");
readfile("tj.jar");
?>
<?php
// This works always
header("Content-Type: text/html; charset=ISO-8859-1");
header("\n\n190\n");
readfile("../_JAVARES/car/jammer.jar");
?>
<?php
// This sometimes fails depending on browser/VM
session_start();
header("Content-Type: text/html; charset=ISO-8859-1");
readfile("tj.jar");
?>
