http_redirect

Issue HTTP redirect

&reftitle.description; `bool` `http_redirect` `string` `url` `array` `params` `bool` `session` false `int` `status` 0

Redirect to the given url.

The supplied `url` will be expanded with `http_build_url`, the `params` array will be treated with `http_build_str` and the session identification will be appended if `session` is true. The HTTP response code will be set according to `status`. You can use one of the redirect constants for convenience. Please see RFC 2616 for which redirect response code to use in which situation. By default PHP will decide which response status fits best.

To be RFC compliant, "Redirecting to <a>URL</a>." will be displayed, if the client doesn't redirect immediately, and the request method was another one than HEAD.

A log entry will be written to the redirect log, if the &link.http.configuration; http.log.redirect is set and the redirect attempt was successful.

- the URL to redirect to
