-----------------------------------

             Summary: sscl is occasionally zero
                 Key: TS-2998
                 URL: https://issues.apache.org/jira/browse/TS-2998
             Project: Traffic Server
          Issue Type: Bug
          Components: Logging
            Reporter: Scott Beardsley


Running ATS 5.0 it looks like sscl in the extended2.log is occasionally zero even for cache misses and HTTP 200 reponses...  Here is how I am finding these cases:

tail -f extended2.log|awk '$23~/TCP_MISS/&&$11~/200/&&$12~/^0/{print $10,$11,$12,$23,$7}'

21452 200 0 TCP_MISS http://search.example.com/search?p=pizza

You can see that pscl ($10) is non-zero but sscl ($12) is zero. Where is ats getting the content from if it isn't coming from the origin? Is this related to the value of the content-length header from the origin? Ideally we would want to see the raw number of bytes coming from the origin.
