Leif Hedstrom updated TS-4351:
------------------------------
Fix Version/s: sometime
> 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
> Fix For: sometime
>
>
> {{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.
