I put this in my /etc/hosts file:

198.252.206.16  stackoverflowtest.com

And when I try stackoverflowtest.com in my browser, I get this squid error: 

ERROR

The requested URL could not be retrieved

The following error was encountered while trying to retrieve the URL: http://stackoverflowtest.com/

Unable to determine IP address from host name stackoverflowtest.com

The DNS server returned:

Name Error: The domain name does not exist.
This means that the cache was not able to resolve the hostname presented in the URL. Check if the address is correct.

Your cache administrator is webmaster.

Instead of this:

Stack exchange
Couldn't find 198.252.206.16
...

Why squid breaks the hostfile ? Any workaround ?

I have a rails app (let's call it myapp) running at www.myapp.com. I want to add a wordpress blog at www.myapp.com/blog. The webserver for the rails app is thin (see the upstream block). The wordpress runs with php-fastcgi.

The rails app works fine. My problem is the following: in /home/myapp/myapp/log/error.log error I get: 

2013/06/24 10:19:40 [error] 26066#0: *4 connect() failed (111: Connection refused) while connecti\
ng to upstream, client: xx.xx.138.20, server: www.myapp.com, request: "GET /blog/ HTTP/1.1", \
upstream: "fastcgi://127.0.0.1:9000", host: "www.myapp.com"

Here is the nginx conf file:

upstream  myapp {
   server   unix:/tmp/thin_myapp.0.sock;
   server   unix:/tmp/thin_myapp.1.sock;
   server   unix:/tmp/thin_myapp2.sock;
}

server {
    listen       80;
    server_name www.myapp.com;
    client_max_body_size 20M;

        access_log /home/myapp/myapp/log/access.log;
        error_log  /home/myapp/myapp/log/error.log error;
        root       /home/myapp/myapp/public;
        index      index.html;

         location / {                             

             proxy_set_header  X-Real-IP  $remote_addr;
             proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_set_header  Host $http_host;
         proxy_redirect    off;

            # Index HTML Files                                                                
            if (-f $document_root/cache/$uri/index.html) {
                rewrite (.*) /cache/$1/index.html break;
        }

            if (!-f $request_filename) {
                proxy_pass http://myapp;
                break;
            }
           #  try_files /system/maintenance.html $uri $uri/index.html $uri.html @ruby;        

         }

         location /blog/ {
             root               /var/www/wordpress;
             fastcgi_index  index.php;

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

             include /etc/nginx/fastcgi_params;
             fastcgi_param  SCRIPT_FILENAME    /var/www/wordpress$fastcgi_script_name;
             fastcgi_pass   localhost:9000;  # port to FastCGI                                           
         }

}

Any ideas why that doesn't work ? How do I make sure that php-factcgi is configured properly ?

Edit: I cant test if fastcgi is running with telnet:

$> telnet 127.0.0.1 9000
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

And it's not.
