Config help needed to create long-polling location

Fri May 7 20:54:08 MSD 2010

Hi All,

I'm trying to use the long polling module. I got it compiled, installed 
and running:-

ian at titan:~$ nginx -V
nginx version: nginx/0.7.65
built by gcc 4.3.3 (Ubuntu 4.3.3-5ubuntu4)
configure arguments: --with-openssl=/usr/lib/ssl/ --sbin-path=/usr/sbin 
--conf-path=/etc/nginx/nginx.conf 
--add-module=/home/ian/sources/nginx_http_push_module-0.69
ian at titan:~$

But I can't get it configured properly.  The address to write messages 
to, appears not to exist whatever I do.

The key part of the configuration is this:-

server {
     listen   80;
     server_name coachmaster.titan.hcs;
     root /home/ian/websites/coachmaster;
     index index.php index.html index.htm;
     error_page   500 502 503 504  /50x.html;
     location = /50x.html {
         root   /var/www/nginx-default;
     }
     location ~ \.php$ {
         fastcgi_pass 127.0.0.1:9000;
         include /etc/nginx/fastcgi_params;
     }
     # now to configure the long polling
     push_store_messages on;
     location /publish {
         push_publisher;
         set $push_channel_id $arg_id;
         push_message_timeout 5m;
         push_max_message_buffer_length 10;
         push_min_message_recipients 0;
     }
     # public long-polling endpoint
     location /activity {
         push_subscriber;
         push_subscriber_concurrency broadcast;
         set $push_channel_id $arg_id;
         default_type  text/plain;
     }
}

When I post to the /publish location I get a 404 error. Always.  When I 
"get" from a file that exists, I get the file content.
When I post to a .php that exists, it gets run and its output is 
returned, so I'm fairly confident that the trouble is in the config file 
or my understanding, not the php.

This is the test script:-
<?php
$host = $_SERVER['HTTP_HOST'];
$url = "http://$host/publish?id=1234";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/json"));
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Accept: text/json"));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  // read data
curl_setopt($ch, CURLOPT_POST, true);            // do a post
curl_setopt($ch, CURLOPT_POSTFIELDS, 'A test message');
$rec_data = curl_exec($ch);
echo "Result\n";
echo $rec_data;
?>

This is the reply:-

Result
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /publish was not found on this server.</p>
</body></html>

If you are wondering why I should do the post from php, it is because I 
want to log the info posted as well, and
check that the poster is logged in properly, neither of which I can do 
in JavaScript.

I would be very grateful if some kind person can spot what I'm doing 
wrong - before I tear out my remaining hair!

Regards

Ian
