I brought a domain in godady and I have Installed Passenger + Nginx on a Linux/Unix(Ubuntu) server and deployed a Ruby app. Now my domain looks something like http://example.com when I try to request from a browser.
But I want my domain to default redirect to www every time it is requested from a browser(like http://www.example.com.).

example.conf

 server 
 listen 80;
 server_name www.example.com example.com;
 # return 301 $scheme://www.example.com$request_uri;
 # Tell Nginx and Passenger where your app's 'public' directory is
 root /var/www/example/public;

 # Turn on Passenger
 passenger_enabled on;
 passenger_spawn_method direct;
 passenger_min_instances 1;
 #passenger_pool_idle_time 0;
 rails_env development;
 passenger_ruby /usr/local/rvm/gems/ruby-2.3.3/wrappers/ruby;
 passenger_sticky_sessions on;

uncommenting the line

return 301 $scheme://www.example.com$request_uri;

is throwing the error

www.example.com redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS

I am forced to manually type www.example.com in the browser. Instead, how can I redirect to www by default?

Any Help is highly appreciated. Thanks in advance!

You basically need two server configuration chunks:

• One for www; to be redirected to base domain only


• One for the base domain

Here is an example to get you started:

server 
 listen 80;
 server_name www.example.com;

 location / 
 # Redirection happens here
 return 301 http://example.com$request_uri;
 



server 
 listen 80 default_server;
 server_name example.com;

 # Other conf directives go here

The easiest way is probably to make use of NGINX if statements. Simply put the following in your virtual host configuration:

if ($host = "example.com") 
 return 301 $scheme://www.$host$request_uri;

and be sure to replace "example.com" with your domain name.

While this is the simplest way I've found, it's not the best. The recommended route is to create a separate server block for non-www, and put the return statement there.
