Thanks Boris for you quick answer !
Can you do that dynamically in the app calling IPF? Through which properties? Or through the endpoint, adding a "&AllowChunking=false" ? I have a Java 8 client like that:
Exchange exchange = new DefaultExchange(getCamelContext());
exchange.getIn().setBody(body);
addWssHeader(securitySamlToken, exchange);
ProducerTemplate template = camelContext.createProducerTemplate();
Exchange result = template.send(endpoint, exchange);
I am not sure how to access the "client" structure...

Stéphane
