SYMPTOMS
A BizTalk HTTP transport may be unsuccessful when the HTTP transport posts messages to the partner. The problem may cause duplicated messages to be sent to the partner and may cause messages to be moved to the suspended queue. The problem occurs if the HTTP 100 and HTTP 200 responses from the partner are in a single Transmission Control Protocol (TCP) packet.



CAUSE
BizTalk Server does not recognize the HTTP 200 response if the HTTP 100 and HTTP 200 responses are in a single TCP packet. This causes it to retransmit the message, which results in duplicated messages to the partner. If all responses from the partner during all retries of a message have the pattern of the HTTP 100 and HTTP 200 responses in a single TCP packet, BizTalk moves the message to the suspended queue.
