Resolution: Won't Fix
Fix Version/s: (was: 4.3)

> Key: HTTPCORE-337
> URL: https://issues.apache.org/jira/browse/HTTPCORE-337
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: Examples
> Affects Versions: 4.2.4
> Reporter: Mike Corneille
> Priority: Minor
>
> Problem: The 302 redirect doesn't work because the "location" header isn't
> properly transposed. By copying all headers from the origin to the client
> respolves the 302 problem. There could be other issues with simply
> transposing all headers, but this is a good fix to add for now...
