3.1.1.4.1 Regular SRMP Message and Receipts
The following figure shows the message sequence for sending a regular or durable SRMP message between two QMs. In this case, the sender is requesting delivery and commitment receipts from the receiver.

Figure 9: Regular SRMP message and receipts
First, the sender sends the SRMP message to the remote host via HTTP transport. The application message payload is included as a MIME attachment, as specified in section 2.2.2. The HTTP transport acknowledges every successful message by replying with "HTTP 200 OK".
Next, the receiver acknowledges receipt of the message by sending a delivery receipt (section 3.1.1.3.1). The commitment receipt (section 3.1.1.3.4) is sent after a delay, when the message is either discarded or picked up by the receiving application.
