Message chunking is set using the Transfer-Encoding: chunked header. To However, some legacy backends might not support chunked messages. To disable sending chunked messages to the backend for a specific API, follow the steps below:

  1. Create an xml XML file with the following content:

    Code Block
    languagexml
    titledisable chunking
    <?xml version="1.0" encoding="UTF-8"?>
    <sequence xmlns="http://ws.apache.org/ns/synapse" name="disableChunkingSeq">
       <property name="DISABLE_CHUNKING" value="true" scope="axis2"/>
    </sequence>
  2. Use the same sequence and apply it as a mediation extension for to the inflow of this particular API, to the inflow. For more details, see Creating per-API extensions. Once the API is published, the chunking will be is disabled for the message that is sent to the backend.
