yourls plugin to send a 302 (temporary) redirect instead of 301 (permanent) for sites where shortlinks may change
This plugin applies across an entire yourls installation - cannot currently be customised per-link. Note that it will only work reliably on new links, since old links will have already been cached in browsers due to the use of 301 headers.
yourls 1.5 or 1.5.1
