Hi,

 

In a Half-proxy configuration you're gonna see:

 

Inbound part of the connection associated tipically with Requests to a Server

 

There's one TCP connection initiated and then established by the client to the BIG-IP device (Client-Side Connection). Then there's another TCP connection initiated and then established by the BIG-IP to the backend server (Server-Side Connection).

 

Outbound part of the connection associated tipically with the Response to the client

 

There's one TCP connection initiated and then established by the Server directly to the client so the response bypass the BIG-IP device, usually via another gateway like a Router (Which do not proxy the connection to the client).

 

I hope this helps.
