Jonathan Moore updated HTTPCLIENT-985:
--------------------------------------
Attachment: via-header.patch
I've uploaded a patch that fixes this issue, including unit tests. One area for
discussion is how to populate the comment section of the Via header (if we want
to include one). Currently the implementation follows the format of the
User-Agent set by DefaultHttpClient, so:
Via: 1.1 localhost (Apache-HttpClient/4.1-alpha3-SNAPSHOT (cache))
This patch is contributed with the permission of my employer.
> cache module should populate Via header to capture upstream and downstream
> protocols

> Key: HTTPCLIENT-985
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-985
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: Cache
> Affects Versions: 4.1 Alpha2
> Reporter: Jonathan Moore
> Attachments: via-header.patch
>
>
> Because the cache module is currently implemented as a decorator that behaves
> like a transparent caching proxy, we need it to correctly populate the Via
> header so that we can preserve the record of which protocol versions were
> used upstream and downstream from the caching module.
> This is a MUST per the RFC:
> http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.45
