If the prefix is set to "/", it means the user does not want to alter
the original URI, so we don't want to insert a new slash before the
original URI.

It is now possible to set or clear a cookie during a redirection. This
is useful for logout pages, or for protecting against some DoSes. Check
the documentation for the options supported by the "redirect" keyword.
(cherry-picked from commit 4af993822e880d8c932f4ad6920db4c9242b0981)
If "drop-query" is present on a "redirect" line using the "prefix" mode,
then the returned Location header will be the request URI without the
query-string. This may be used on some login/logout pages, or when it
must be decided to redirect the user to a non-secure server.
(cherry-picked from commit f2d361ccd73aa16538ce767c766362dd8f0a88fd)
A new "redirect" keyword adds the ability to send an HTTP 301/302/303
redirection to either an absolute location or to a prefix followed by
the original URI. The redirection is conditionned by ACL rules, so it
becomes very easy to move parts of a site to another site using this.
This work was almost entirely done at Exceliance by Emeric Brun.
A test-case has been added in the tests/ directory.
