Favicon showing up in multiple Rails apps

I'm having an unusual problem - I uploaded a favicon into one of my rails applications into the application.html.erb file into the head using this code: <%= favicon_link_tag 'favicon.ico' %>. This works fine, the favicon shows up, but when I close that application and open a new one into my localhost:3000, the same favicon is showing up, but there's no code in that application for it, in the head nor in the public/favicon file. Any idea how this can be happening?

Solution

  • That's probably because of the cached version on browser for address localhost:3000 i.e. 127.0.0.1:3000. Try changing the port number to something else. For example: localhost:3001 by running this command:

    rails s -p 3001

    You won't see the same favicon now.
