# Redirects the browser to the target specified in +options+. This parameter can take one of three forms:
#
# * <tt>Hash</tt> - The URL will be generated by calling url_for with the +options+.
# * <tt>Record</tt> - The URL will be generated by calling url_for with the +options+, which will reference a named URL for that record.
# * <tt>String</tt> starting with <tt>protocol://</tt> (like <tt>http://</tt>) - Is passed straight through as the target for redirection.
# * <tt>String</tt> not containing a protocol - The current protocol and host is prepended to the string.
# * <tt>:back</tt> - Back to the page that issued the request. Useful for forms that are triggered from multiple places.
# Short-hand for <tt>redirect_to(request.env["HTTP_REFERER"])</tt>
#
# Examples:
# redirect_to :action => "show", :id => 5
# redirect_to post
# redirect_to "http://www.rubyonrails.org"
# redirect_to "/images/screenshot.jpg"
# redirect_to articles_url
# redirect_to :back
#
# The redirection happens as a "302 Moved" header unless otherwise specified.
#
# Examples:
# redirect_to post_url(@post), :status=>:found
# redirect_to :action=>'atom', :status=>:moved_permanently
# redirect_to post_url(@post), :status=>301
# redirect_to :action=>'atom', :status=>302
#
# When using <tt>redirect_to :back</tt>, if there is no referrer,
# RedirectBackError will be raised. You may specify some fallback
# behavior for this case by rescuing RedirectBackError.
