Pull MEP
ebMS 3.0 / AS4 MEP binding suited to peers without a public listening endpoint.
Definition
On the Pull binding the sender queues the message against an MPC (Message Partition Channel); the receiver sends an eb:SignalMessage/PullRequest referencing that MPC and gets the UserMessage in the HTTP response. Useful when the receiver sits behind a firewall or NAT with no reachable endpoint. AS4 defines "One-Way/Pull" as one of its conformance profiles.
Origin
Defined by the Pull binding and PullRequest of OASIS ebMS 3.0 Part 1 (section 5.2.3.2) and profiled by the conformance MEPs of OASIS AS4 Profile of ebMS 3.0 Version 1.0.
