Some legacy back ends might not support chunked messages. Message chunking is set using the Transfer-Encoding: chunked header. To disable sending chunked messages to the backend for a specific API, follow the steps below:
Create an xml file with the following content:
disable 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>
Use the same sequence and apply it as a mediation extension for this particular API, to the inflow. For more details, see Creating per-API extensions. Once the API is published, the chunking will be disabled for the message that is sent to the backend.
You can apply the same mediation extenstion to the out sequence as well, to stop chunked messages being sent to the client.
