3.3.5 Message Processing Events and Sequencing Rules

The relay receives a SQM message from the client via an HTTP POST sent by using the proxy port configured on the SQM service. If the POST contains a payload that adheres to the SQM format, the message payload is augmented with an additional data point that identifies the relay. This is an additive change only. The payload is then repackaged and sent to the SQM service by using SSL over port 443.

All other protocol messages are directly sent directly through the proxy without modification in a similar manner, where the first transmission from the client to the relay is communicated over HTTP and the second transmission is communicated using over SSL by using port 443. If the proxy receives a message that is not of a recognized format, the message is sent to the SQM service with no changes.
