## Header Management

In the Platform Edition of the Application Server, the `Enumeration` from `request.``getHeaders()` contains multiple elements. In the Enterprise Edition, this `Enumeration` contains a single, aggregated value.

The header names used in `HttpServletResponse.add` XXX `Header()` and `HttpServletResponse.set` XXX `Header()` are returned differently to the HTTP client from the Platform Edition and the Enterprise Edition of the Application Server. The Platform Edition preserves the names as they were created. The Enterprise Edition capitalizes the first letter but converts all other letters to lower case. For example, if `sampleHeaderName2` is used in `response.addHeader()`, the response name in the Platform Edition is unchanged, but the response name in the Enterprise Edition is `Sampleheadername2`.
