/subdomain duplicates when using PassengerBaseURI

[ghost]

Issue report

Question 1: What is the problem? I tried setting up passenger with subdomain configuration, but it won't work as much as I expected. I expected url like http://my-rails.app/app1, but it actually behaved like http://my-rails.app/app1/app1.
I'm using symbolic link, which links from /var/www/html/app1 to /home/username/rails-app and on my server, this application works alone.
If there is no PassengerBaseURI, it works as expected. here is my passenger configuration file.

<VirtualHost *:80>
  RailsEnv staging
  PassengerEnabled on
  ServerName my-rails.app
  LogLevel debug
  DocumentRoot /var/www/html/app1

  Alias /app1 /var/www/html/app1
  <Location /app1 >
    PassengerBaseURI /app1
    PassengerAppRoot /home/username/rails-app
    SetEnv DATABASE_URL xxxxx://xxx:xxx@xx.xx.xx.xxx:xxxx/xxxx
    SetEnv SECRET_KEY_BASE xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    SetEnv RAILS_RELATIVE_URL_ROOT /app1
  </Location>
  <Directory /var/www/html/app1>
    Allow from all
    Options -MultiViews
    Require all granted
  </Directory>
</VirtualHost>

Try changing «<VirtualHost *:80>» to «» and so on for all your virtual hosts. See https://httpd.apache.org/docs/2.4/vhosts/examples.html .

Are you seeing incorrect links generated or is your app receiving requests with incorrect paths?

Thank you for reply and I'm sorry to my late response, but there is still incorrect response from server. My application server said The requested URL /app1/sign_in/path was not found on this server. and return 404. I check my symlink but it certainly link to application's public folder.

I'm sorry, to clarify before it seemed that you were receiving requests like http://my-rails.app/app1/app1 and in this reply you only have one instance of /app1. Do you want the /app1 stripped off completely or are you seeing two copies of /app1?
