Need Guidance: IDoc to HTTP Scenario

Hi Experts,

Due to some performance issues, I have decided to go for IDoc to HTTP Scenario. My only problem is that, the HTTP will send a response in return to the request sent by the IDoc.

Please let me know if there is a possibility that I can have asynchronous calls on the sender side (i.e. IDoc) and Synchronous calls on the Receiver side (i.e. HTTP) as the request sent by IDoc gets a response in return from HTTP?

R/3 -

> (Async)-->PI ->(Sync) -> HTTP

Thanks in Advance,

Arkesh
