In my app

user can access to the community page just like this
http://example.com/communities?tag=lovely

then if I try to go back to the previous page. I always get this message 

Are you sure you want to send a form again

This only appears when it’s accessed from Safari

How can I avoid that. I don’t want user to see it every time when they go back.

routes.rb

resources :communities

    One way to avoid this problem is to make your POST responses return a redirect (HTTP 301 or 303) to a new page, which the browser then requests with GET. Going back should (though doesn’t always) fetch the original form page, not the POST.

    In Rails, this run-around often looks like this:

    1. client GETs /foos/new
    2. server returns HTML with <FORM method='POST' action='/foos'>
    3. client POSTs /foos (with params)
    4. server creates a new Foo with id 123
    5. server returns redirect to /foos/123
    6. client GETs /foos/123
    7. server returns HTML for newly created Foo
