[jira] Created: (HTTPCLIENT-985) cache module should populate Via
header to capture upstream and downstream protocols
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
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.

[jira] Updated: (HTTPCLIENT-985) cache module should populate Via

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.
