Saliya Ekanayake commented on SYNAPSE-408: ------------------------------------------ The alternative approach you are suggesting was in fact there in Synapse before https://issues.apache.org/jira/browse/SYNAPSE-392. We have used the serialize() and serializeAndConsume() methods to find the content length and then to send it out respectively. This, however, resulted in different outputs as the latter method adds an empty SOAP header element where as the former does not add such if it's not available in the original XML. However, IMHO serializing twice will affect the performance with respect to time as well (pls. correct me here if I am wrong).
