All Known Implementing Classes:

DefaultRefererResult

public interface RefererResult
extends View

Redirects or forwards to the Referer. "The Referer[sic] request-header field allows the client to specify, for the server's benefit, the address (URI) of the resource from which the Request-URI was obtained (the "referrer", although the header field is misspelled.)" -- http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html As Referer is not a mandatory header, you can specify a fallback result, to be used when referrer is not specified: try { result.use(referer()).redirect(); } catch (IllegalStateException e) { result.use(logic()).redirectTo(AnyController.class).anyMethod(); }
