http_redirect - Issue HTTP redirect

SYNOPSIS
       bool http_redirect ([string  $url], [array  $params], [bool  $session = false], [int  $status])

DESCRIPTION
	Redirect to the given url.

	The  supplied $url will be expanded with http_build_url(3), the $params array will be treated with http_build_str(3) and the session iden-
       tification 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 INI settinghttp.log.redirect is set and the redirect attempt was successful.

PARAMETERS
	      o $url
		- the URL to redirect to

	      o $params
		- associative array of query parameters

	      o $session
		- whether to append session information

	      o $status
		- custom response status code

RETURN VALUES
	Returns FALSE or exits on success with the specified redirection status code. See the INI settinghttp.force_exit for what "exits" means.
