What do you mean?

Do you get error when you use redirect\_to?

Rails API ([api.rubyonrails.org](http://api.rubyonrails.org)) for redirect\_to says:

When using redirect\_to :back, if there is no referrer,  
RedirectBackError will be raised. You may specify some fallback  
behavior for this case by rescueing RedirectBackError.

The Referer header is usually sent with a request by a browser if the  
user goes to the page by clicking a link, and it contains the url of  
the page with that link. There is no Referer header if the user just  
types the address in the address bar, for example.
