# This test reproduces the bug described in https://github.com/alibaba/higress/issues/3571
# When plugin A (transformer) modifies headers causing a reroute, plugin B (custom-response)
# should see the NEW route name in its matchRule evaluation. Due to a bug in ROUTE_NAME
# property resolution, the stale old route name is returned after clearRouteCache().
