Tim's questions

i have a large site with lot of pages that almost never change, right now i am using two memcache servers (amazon elasticache), but this its really expensive.

Thats why for this files that barely never change i want to upload them to amazon s3 and shutdown 1 memcache server.

Here is my conf;

location ~ /longterm/(.*){
   proxy_pass http://amazonS3bucket;
   proxy_intercept_errors on;
   proxy_next_upstream http_404;
   error_page 404 503 = @fallback_memcached
}

location @fallback_memcache {
   set $memcached_key $uri;
   memcached_pass     name:11211;
   error_page         404 @fallback;
}

location @fallback {
   try_files $uri $uri/index.html
}

I dont know why but the config doesnt work on the final fallback; if i got an amazon S3 hit it works, if i got an amazon S3 miss and a memcache hit it works, but if i got an amazon S3 miss then a memcache miss when it try to resolve the las fallback it fails.

I am also thinking in use the amazon s3 fuse http://code.google.com/p/s3fs/ instead of the proxy pass i think it would be easier for implement, i would also be less performant?

2.1, i am also using the amazon elastic cache service (its a memcached server)

Nginx has a clever feature that uses memcached for common get request, but if is a post request dont use memcached, is anyway to disable this feature?

Here is my configuration;

location /{
    set_md5  $memcached_key "http://$server_name$uri";
    memcached_pass cacheviews.bsd7na.0001.use1.cache.amazonaws.com:11211;
    default_type text/html;
    add_header Content-Encoding gzip;
    error_page 405 404 = @fallback;
}

location @fallback{
    internal;
    gzip_types text/css text/plain application/atom+xml application/x-javascript;
    gzip_vary on;
    #  stuff to do a normal render of the page
}

I've got a simple nginx configuration;

server{
  servername localhost;
  root /var/www/webroot;

  location / {
    set_md5  $memcached_key $uri;
    index  index.php index.html;
    try_files $uri $uri/ @cache;
  }

  location @cache  {
    memcached_pass localhost:11211;
    default_type text/html;
    error_page 404  @fallback;
  }

  location @fallback{
    try_files $uri $uri/ /index.php?url=$uri&$args;
  }

  location ~ \.php$ {
    fastcgi_param MEM_KEY $memcached_key;
    include /etc/nginx/fastcgi.conf;
    fastcgi_index  index.php;
    fastcgi_intercept_errors on;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
  }
}

I've got a CakePHP helper that saves the view into memcached using the MEM_KEY parameter. I have tested it and it's working, however, nginx is always going to the @fallback direction. How can I go about troubleshooting this behavior? Would could the problem be?
