This function returns a valid HTTP date regarding RFC 822/1123 looking like: "Wed, 22 Dec 2004 11:34:47 GMT"
-This function returns an absolute URI constructed from url.
-If the url is already abolute but a different proto was supplied,
-only the proto part of the URI will be updated. If url has no
-path specified, the path of the current REQUEST_URI will be taken.
-The host will be taken either from the Host HTTP header of the client
-the SERVER_NAME or just localhost if prior are not available.
Some examples:
-
-url = "page.php" => http://www.example.com/current/path/page.php
-url = "/page.php" => http://www.example.com/page.php
-url = "/page.php", proto = "https" => https://www.example.com/page.php
