William Bardwell created TS-2912:
------------------------------------
Summary: HEAD transaction on stale entry deletes cache entry
Key: TS-2912
URL: https://issues.apache.org/jira/browse/TS-2912
Project: Traffic Server
Issue Type: Bug
Components: HTTP
Reporter: William Bardwell
On a stale cache entry a HEAD gets tunneled to the origin, but when a 200 comes
back HttpTransact::handle_cache_operation_on_forward_server_response(State* s)
deletes the cache entry, it seems like it should just ignore it (or check
ETag/Last-Modified and maybe delete if those don't match, but not
unconditionally.)
I am seeing this with 4.2.X with a plugin fiddling with stuff, but the code
looks the same in trunk, line 4318 looks like the problem line.
