Redireccionamientos/Browser Redirect

You can trigger a browser redirect with the redirect helper method:

get '/foo' do
  redirect to('/bar')
end

Any additional parameters are handled like arguments passed to halt:

redirect to('/bar'), 303
redirect 'http://google.com', 'wrong place, buddy'

You can also easily redirect back to the page the user came from with redirect back:

get '/foo' do
  "<a href='/bar'>do something</a>"
end

get '/bar' do
  do_something
  redirect back
end

To pass arguments with a redirect, either add them to the query:

redirect to('/bar?sum=42')

Or use a session:

enable :sessions

get '/foo' do
  session[:secret] = 'foo'
  redirect to('/bar')
end

get '/bar' do
  session[:secret]
end
