This is a good point, and noted.

I have added two additional unit tests and will attach that diff as well.

>             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
>              Labels: patch
>             Fix For: 4.1.2, 4.2, Future
>         Attachments: ResponseContent.diff, TestStandardInterceptors.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.
