response, send back 304 if possible [crc=304]" breaks akamaihd.net live
streaming
Nikolai Gorchilov created TS-3995:
-------------------------------------
Summary: "[hcoofsr] conditional request, 200 response, send back 304 if possible [crc=304]" breaks akamaihd.net live streaming
Key: TS-3995
URL: https://issues.apache.org/jira/browse/TS-3995
Project: Traffic Server
Issue Type: Bug
Components: Cache, Core, HTTP
Reporter: Nikolai Gorchilov
Caching proxy running ATS 5.3.x (5.3.0, 5.3.1, 5.3.2 all fail) with proxy.config.http.cache.when_to_revalidate = 4 breaks akamaihd.net live streaming by overwriting non-cacheable origin response from 200 to 304 to a client conditional request.
Here's a log of all request and response headers for a single transaction, collected via debug:
