Bug 1145713 - Add 302 redirects from TBPL to Treeherder/mcMerge * Redirects mcMerge to the new paas instance. * Excludes the cache directory from all rules, so we can still access the revision info / data-import logs. * Returns a 403 forbidden rather than redirecting, for things under php/, so API consumers get a more obvious failure mode. * Redirects common trees to the appropriate URL on Treeherder (for all others, redirects to the Treeherder homepage). * For the common trees, preserves/converts the pusher or revision filter params, but removes any others since they'd require overly complex mapping to their equivalents on Treeherder. * For anything else, just redirect to the Treeherder homepage.
