--------------------------------
Summary: Turing off cache in remap rule has unexpected Proxying
cases
Key: TS-3350
URL: https://issues.apache.org/jira/browse/TS-3350
Project: Traffic Server
Issue Type: Bug
Reporter: Miles Libbey
We are using
@plugin=conf_remap.so @pparam=proxy.config.http.cache.http=0
in a remap rule.
We see 2 unexpected proxying cases:
1) Cache-control: only-if-cached.
Normally a request with this header will only return a 200 if the object is
cached (504 if not cached). We always get a 200 OK for these urls, suggesting
the request is forwarded to the origin. (If the X-Debug plugin is installed,
and X-Debug:X-Cache is also sent, the response indicates the cache was skipped.
2) PURGE.
When we issue a PURGE request for urls matching this remap, it appears that the
PURGE is proxied to the origin server.
