Help translating Apache RewriteRules - Again, Thoroughly

[Chris Cortese]

I'm still stumped on this one.  Can anyone tell why I'm getting an 
endless loop?  Firefox gives:

[code]
The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for this 
address in a way that will never complete.
   *   This problem can sometimes be caused by disabling or refusing to 
accept
           cookies.
[/code]



Machine:
[code]
. Ubuntu Karmic Koala fully-upgraded/updated, VM running on VMWare 
Workstation 6.5 running on Windows XP
. nginx 0.8.35 built from source
. php-5.3.2 with php-fpm
[/code]



Working .htaccess Apache file:
[code]
Options -Indexes

RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^([0-9a-zA-Z\/\-\_\@]+)$ index.php?demand=$1 [QSA,L]
#RewriteRule ^(.*)$ index.php?demand=$1 [NC,L]


<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>
[/code]



My Nginx conf file:
[code]
server {
    listen 80;
   server_name  domain.com.vmware;

   access_log  /usr/local/nginx/logs/domain.com.access.log;
   error_log /usr/local/nginx/logs/domain.com.error.log debug;

   root /home/mylinuxuser/www/live/domain.com;
   index index.php;

   location / {
     fastcgi_pass  127.0.0.1:9000;
     fastcgi_param SCRIPT_FILENAME 
/home/mylinuxuser/www/live/domain.com/index.php;
     include /usr/local/nginx/conf/fastcgi_params;
   }

   location ~ ^/([0-9a-zA-Z\/\-\_\@]+)$ {
     fastcgi_pass  127.0.0.1:9000;
     fastcgi_param SCRIPT_FILENAME 
/home/mylinuxuser/www/live/domain.com/index.php;
     fastcgi_param QUERY_STRING      demand=$1;
     include /usr/local/nginx/conf/fastcgi_params0;
   }
}
[/code]

Here is the 5200-line debug output from the error log when only 
requesting http://domain.com

http://pastebin.com/6PLyC3r8



Note:  fastcgi_params is unmodified from nginx distribution.
	fastcgi_params0 is identical except it lacks QUERY_STRING setting


Note2:  I didn't write the web code.  There is PHP code doing a 
header("Location:... etc") call, in order to make clean URLs.  Still, if 
the PHP code works with the Apache .htaccess, it must be possible to 
have it work with Nginx configuration.

Can anyone help?


Thanks,
Chris
