Hi all,<br><br>I was wondering what the common way is to call one gen_server, have this call forwarded to another gen_server, and have this other server reply to the client. One way of doing this is by having the first gen_server send a cast to the second gen_server, including the PID of the client, and then respond with a noreply. The second gen_server handles the cast by explicitly responding to the client using gen_server:reply() - using the PID sent by the original gen_server, of course. This seems to work, but it feels like a clumsy way to do it - isn't there a better way?<br>
<br>At the end of the 'OTP Introduction' chapter, Armstrong's book 'Programming Erlang' hints that this is documented in the OTP Design Principles, but I cannot really find it there - am I overlooking something or is this covered elsewhere?<br>
<br>Thanks in advance,<br><br>Jeroen Koops<br>
