Why does the Android Servlet implementation use an incorrect chunked encoding format?

As documneted in the following page on the SmartSDK resource:  \en\guide_ml\400-02-0102.htm the current SmartSDK does not support chuncked transfer.

3-2. Response body
See the specification document for each web application.
- Chunked transfer is not available. Add Content-Length header.

This spec/limitation comes from controller network module's current capability.  So, each servlet application needs to set content-length by itself.  Servlet Sample application also set content-length when sending file as a response.
