Allow Overwriting of Content-Length & Transfer-Encoding Headers
---------------------------------------------------------------

                 Key: HTTPCORE-264
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-264
             Project: HttpComponents HttpCore
          Issue Type: Improvement
          Components: HttpCore
    Affects Versions: 4.1.2, 4.2-alpha1, 4.2, Future
         Environment: n/a
            Reporter: William R. Speirs
            Priority: Trivial
             Fix For: 4.1.2, 4.2, Future
         Attachments: ResponseContent.diff

Currently the ResponseContent interceptor will throw an exception if the Content-Length or Transfer-Encoding headers are found in the response. I am proposing a patch which adds 2 new constructors to ResponseContent. These new constructors allow ResponseContent to overwrite the Content-Length and/or Transfer-Encoding headers if they're already found instead of throwing an exception.

The biggest use I see for this is in a reverse proxy. The response from the proxied server will already have proper Content-Length and Transfer-Encoding headers. However, this interceptor throws an exception in this case. The simple answer is to remove this interceptor; however, I would like to clean-up any response where these headers might be missing.

The default constructor is to thrown an exception if these headers are found.
