◆ redirect() [1/2]

void Response::redirect	(	const QString &	url,
		quint16	status = Found )

Causes the response to redirect to the specified URL. The default status is 302. This is a convenience method that sets the Location header to the redirect destination, and then sets the response status. You will want to return false or c->detach() to interrupt the normal processing flow if you want the redirect to occur straight away.

Note: Do not give a relative URL as $url, i.e: one that is not fully qualified ("http://...", etc.) or that starts with a slash "/path/here". While it may work, it is not guaranteed to do the right thing and is not a standard behaviour. You may opt to use uriFor() or uriForAction() instead.

Definition at line 255 of file response.cpp.

		quint16	status = Found )

◆ redirectSafe()

void Response::redirectSafe	(	const QUrl &	url,
		const QUrl &	fallback )

Open Redirect Vulnerability is when you get an user provided URL and redirect to it without checking if it's safe.

This can be used on login forms that receive some "redir" parameter that once logged in allows the user to go straight to that page instead of some home page.

It's then possible to receive a link like http://example.com/login?redir=http://exemple.com/login notice how both domain names are similar for malicious porpuses, once logged in it redirects to a similar login page that will pretent the auth didn't work, user might then type their credentials on that page.

This method validades that the url scheme, domain name and port are the same of the request to your server if it isn't it will send the user to fallback url that you know it's safe. If you need to redirect the user to some other domain/port validate the URL manually an use the regular

		const QString &	reason = {} )

Sends a WebSocket close frame, with both optional close code and a string reason.

Note: This method does not emit Request::webSocketClosed() signal. If you need to track when the connection was closed, the proper way is to rely on Context::destroyed() signal.

Note: Most WebSockets client doesn't handle when a call to a WebSocket endpoint ends on an HTTP authentication failure or other HTTP status that is not the update. Due that it's best to always do the proper websocket handshake and then
