Masakazu Kitajo created TS-4351:
-----------------------------------
Summary: FetchSM shouldn't expose unprotected response headers
Key: TS-4351
URL: https://issues.apache.org/jira/browse/TS-4351
Project: Traffic Server
Issue Type: Improvement
Components: Cleanup
Reporter: Masakazu Kitajo
{{FetchSM}} exposes a member variable {{HTTPHdr client_response_hdr}} and
anybody can modify headers in it. However, such modification breaks
{{FetchSM}}'s internal state, and it results unexpected behavior.
To avoid such modification, {{client_response_hdr}} shouldn't be exposed
directly and {{FetchSM}} should have a getter which returns the headers with
{{const}} modifier.
It sounds easy but we need to fix an other issue (TS-4350) first, because
operations against {{const HTTPHdr}} are limited unreasonably.
