Question: I'm in my applications controller and I have a url string. How do I tell the app to open the url in the browser in a new window. Is there a way to set the target to blank?

For example

```
def link
  @url = 'www.google.com'
  ****??? Open @url ?? *** with target blank?
end

```

Answer: 
This is not possible to do directly from the controller. Using `redirect_to @url` has the effect of opening an URL in the same "window", as it simply sends a HTTP redirect instruction back to the browser. `redirect_to` is not capable of opening new windows. The controller resides on the server side, and opening a new window belongs to the client side. 

Some options:

a) render a link with `<%= link_to 'Google', 'google.com', :target => '_blank' %>` or `<a href="google.com" target="_blank">Google</a>` which the user can click on in a new view

b) use JavaScript to open the link automatically, but beware that browsers may treat this as a popup and block it

By combining these options you can open links in new window for browsers/users who allow it, and fall back to a regular URL in case that didn't work.
Well, it's not that you **CAN'T** do it, it's just kind of a convoluted process. I did this in a project I'm working on. Basically, it's a mixture of Rails goodness and Javascript. I simply passed a flash notice on creation of an instance, and then used a script to set that flash notice equal to a js variable, and a redirect\_url. If that particular flash notice pops up on that page, it redirects in the js script. Like I said, it's **hack hack hack**, but it works for my purposes.
