codeigniter $uri getting mangled with SCRIPT_NAME from nginx - El Forum - 06-06-2011

[eluser]Unknown[/eluser]
I am running nginx 1.04 and CI 2.02.

After spending a couple of days learning more than I wanted to on nginx configs and location rewrite rules, I think there may be a problem with CI. I have spent these last two days on the irc with no relief - I would very much appreciate some guidance. I just started experimenting with CI after having tried out rails. I like this lean and well documented framework and the frustration I've had to get this going is probably unusual. I am looking to the CI community to offer some advice and help, so thanks for reading so far Smile.

I get a "No URI present. Default controller set" regardless of changes in nginx.conf and config.php (different protocols). I have settled on the REQUEST_URI protocol and though nginx passes the correct SCRIPT_NAME, it gets mangled in the URI.php.

Code:
log_message('debug', "**********".$uri);  // valid $uri
$uri = substr($uri, strlen($_SERVER['SCRIPT_NAME']));
log_message('debug', "**********".$uri);        //$uri is blank


Because the $uri is blank, I get this in my CI logs:

Code:
DEBUG - 2011-06-06 18:35:12 --> No URI present. Default controller set.

Please see the attached ci_config.php.txt for the full configuration, but here is the important stuff:
Code:
#config.php

$config['base_url']    = 'http://www.example.net/ci/';
$config['index_page'] = 'index.php';
$config['uri_protocol']    = 'REQUEST_URI';
$config['url_suffix'] = '';

Here is debug log from nginx.conf that shows that REQUEST_URI is resolved correctly. Also "echo $_SERVER[REQUEST_URI]" shows up correctly in the output of the default controller. The text below is just some important stuff, but please see attachment for a complete log.
Code:
