Leif Hedstrom updated TS-3740:
------------------------------
Fix Version/s: 6.1.0
> header_rewrite plugin: set-redirect doesn't work with SEND_RESPONSE_HDR_HOOK
> ----------------------------------------------------------------------------
>
> Key: TS-3740
> URL: https://issues.apache.org/jira/browse/TS-3740
> Project: Traffic Server
> Issue Type: Bug
> Components: Plugins
> Reporter: Gancho Tenev
> Fix For: 6.1.0
>
>
> DESCRIPTION:
> ATS header_rewrite plugin set-redirect operation doesn't work with
> SEND_RESPONSE_HDR_HOOK. Please see the debugging notes below for more info.
> HOW TO REPRODUCE:
> Here is a sample plugin configuration files that reproduce the problem
> $ cat /opt/ats/etc/trafficserver/remap.config
> map http://p1 http://h1:8001 \
> @plugin=header_rewrite.so
> @pparam=/opt/ats/etc/trafficserver/header_rewrite.config
> $ cat /opt/ats/etc/trafficserver/header_rewrite.config
> cond %{SEND_RESPONSE_HDR_HOOK}
> cond %{STATUS} =502
> set-redirect 302 http://p0/%{PATH} [QSA]
> DEBUGGING NOTES:
> Both conditions in the header_rewrite.config are evaluated correctly but
> set-redirect has no effect and the response to the UA is not modified as
> expected. After some debugging it turned out that if the set-redirect
> (OperatorSetDestination::exec) is not called from the remap plugin it has no
> effect. The header_rewrite plugin creates a continuation to be called from
> SEND_RESPONSE_HDR_HOOK (TSHttpHookAdd()). OperatorSetDestination::exec
> doesn't have code to handle the case when the set-redirect operation is _not_
> called directly from the remap plugin (TSRemapDoRemap()).
