ID: 36076 User updated by: brian at blueo2 dot com Reported By: brian at blueo2 dot com -Status: Feedback +Status: Open Bug Type: HTTP related Operating System: FreeBSD 5.4,6.0,amd64 PHP Version: 5.1.2 New Comment:
I am trying to get a single script that will display this particular issue, but so far, the only way I have been able to reproduce it reliably is with Flash loading a bunch of URLs in the background, and then clicking on a new page on the same server (such as the logo on the main page). As an example of the behaviour, you can go to http://music.blueo2.com/?a=artist_Profile&cid=1, open up the song list, and play a bunch of the samples at the same time. As they are playing, click on any other link on the site. It is pretty easy to reproduce this way, but it doesn't happen with, say, only one other stream coming in. I am thinking that this may be an issue with pipelining, but that is a complete stab in the dark. I could try and get a tcpdump of the traffic, if that would help. I will also try and make a single script which can replicate this issue. I was thinking of re-assigning this to another category, as the problem really isn't with HTTP functions. I mis-read the category list. I don't know if this is an Apache2 issue or a scripting engine issue, or general web server issue. It's basically the end of another request coming in on a new request before the HTTP/1.1 response header arrives. I would be very happy to work with someone on a limited access account with access to our source to help find where the issue is, if there is some way we can work together. We're completely strapped for cash, otherwise I would offer to pay someone for help. I'll pay out-of-pocket a couple hundred for someone to track this down with me.

To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2006-01-19 01:51:37] brian at blueo2 dot com Description: ------------ 1) Loading several URLS that are running fread operations and displaying the binary output to the browser 2) While those URLs are still processing (using a Flash app), redirect through a <a href> link to another PHP pahe 3) Data is presented before the HTTP/1.1 response header from a previous request. Reproduce code: --------------- <?php $fp = fopen('/dev/zero', 'ro'); while ($d = fread($fp, 1024)) { echo $d; flush(); } ?> Expected result: ---------------- Not getting the results from previous requests before HTTP headers. Actual result: -------------- Data from previous request before HTTP/1.1 200 OK and additional headers. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=36076&edit=1
