Subject: [PATCH v2 1/6] http: simplify update_url_from_redirect
Date: Tue, 6 Dec 2016 13:24:29 -0500 [thread overview]
Message-ID: <20161206182429.6jp23tltvlznrh2p@sigill.intra.peff.net> (raw)
In-Reply-To: <20161206182414.466uotqfufcimpqb@sigill.intra.peff.net>
This function looks for a common tail between what we asked
for and where we were redirected to, but it open-codes the
comparison. We can avoid some confusing subtractions by
using strip_suffix_mem().
