target
should be anything responding to to_s. To check or
modify the URI the redirect will go to you may pass a block, the result
value of the block is ignored:
redirect("/"){|uri| uri.scheme = 'http' } redirect("/"){|uri| uri.host = 'secure.com' if uri.scheme =~ /s/ }
options
may contain:
:scheme => "http" | "https" | "ftp" | ... :host => "localhost" | "foo.com" | "123.123.123.123" | ... :port => 7000 | "80" | 80 | ... :status => 302 | 300 | 303 | ... :body => "This is a redirect, hold on while we teleport" | ... :raw! => true | false | nil | ...
Note that all options are optional and you may just pass a
target
.
