rewritecond for nginx

[Chris Cortese]

Thanks Igor.  I moved towards the "location" style you described.  I got 
rid of a lot of extra stuff and I moved all but one vhost (conf.d file) 
out of the conf.d directory.

Somehow I broke stylesheets and images.

Also, my cgi stuff is still going to index.php.

This is codeigniter framework, so urls that have /controller/model 
should get passed to index.php.  So, http://mysite.com/search/metro 
should become http://mysite.com/index.php?q=search/metro.  This part is 
happening.  However, I don't want the rewrite to happen for /images, 
/javascript, /style, /tmp, /filestore, etc.  Then also I want the 
/cgi-bin to be handled by fcgiwrap.  Right now if I go to 
http://mysite.com/cgi-bin/test.pl, it is still getting sent to index.php.

This is my config file (domain name here changed to "mysite.com"):

server {
  listen   81;
  server_name  dev.mysite.com;

  root /home/my_linux_user/www/dev/mysite/trunk/html/public;
  index index.php;

  access_log  /var/log/nginx/dev_mysite.access.log;
  error_log /var/log/nginx/dev_mysite.error.log;

  if ($request_filename ~ javascript) {
    rewrite ^/javascript/(.*)$ /combine.php?type=javascript&files=$1 last;
  }

  location /tmp/ {
    rewrite ~/(.*)$ /$1 last;
  }

  location /filestore/ {
    rewrite ~/(.*)$ /$1 last;
  }

  location /cgi-bin/ {
    fastcgi_pass unix:/tmp/cgi.sock;
    include /etc/nginx/perl_fcgiwrap_params;
  }

  if (!-e $request_filename) {
    rewrite ^/(.*)$ /index.php?q=$1 last;
  }

  location ~* (jpg|jpeg|gif|png|js|css) {
      expires    30d;
      access_log off;
  }

  location ~ /index.php {
    fastcgi_pass  127.0.0.1:10005;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME 
/home/my_linux_user/www/dev/mysite/trunk/html/public$fastcgi_script_name;
    include /etc/nginx/fastcgi_params;
  }
}
