Conan Wang commented on TS-973:
-------------------------------
seem there is no way to set a Via header like:
bq. "Via: http/1.1 conan-mac (ApacheTrafficServer/3.1.4-unstable)".
Setting proxy.config.http.insert_response_via_str to 1 or 2 get same debug
header:
bq. Via: http/1.1 conan-mac (ApacheTrafficServer/3.1.4-unstable [uScMs f p eN:t
cCMi p s ])
> Effect of proxy.config.http.insert_response_via_str /
> proxy.config.http.insert_request_via_str conflicts with documentation

> Key: TS-973
> URL: https://issues.apache.org/jira/browse/TS-973
> Project: Traffic Server
> Issue Type: Bug
> Components: Configuration, Documentation
> Affects Versions: 3.1.0, 3.0.1
> Reporter: Arno Toell
> Assignee: Leif Hedstrom
> Priority: Minor
> Fix For: 3.1.1
>
> Attachments: TS-973.diff
>
>
> The documentation on
> http://trafficserver.apache.org/docs/v2/admin/files.htm#records.config tells:
> {quote}
> proxy.config.http.insert_response_via_str
> You can specify one of the following:
> 0 = no extra information is added to the string.
> 1 = all extra information is added.
> 2 = some extra information is added.
> {quote}
> However changing the value does not really seem to affect verbosity of the
> reponse header. Apparently 1/0 only triggers "on" or "off" respectively.
> Instead, there seems to be an undocumented setting called
> _proxy.config.http.verbose_via_str_ which _seems_ affect the verbosity of the
> request/response header.
> This holds likewise for _proxy.config.http.insert_request_via_str_.
> So, either:
> * restore the old behavior which changed the verbosity depending on the value
> of the _insert_response/request_via_str_
> * update the docs reflecting the new situation
