PI to ECC via ABAP Proxy - Outbound Queue for HTTP

Dear Experts,

Is there any Outbound Queue for HTTP?

I've a interface scenario where the receiver is SAP ECC and the receiver adapter XI ABAP proxy. As I see in the communication channel the transport protocol used is HTTP. So I think could there be an outbound queue to manage HTTP connection when PI send the data to SAP ECC?

Just like when we are sending IDocs to ECC via tRFC, we could check if the IDoc has really been sent to ECC by checking in tcode SM58 (Outbound tRFC).

In case for ABAP Proxy via HTTP, is there any similar connection to SM58 (IDoc via tRFC)?

Thank you,
