RE: Local Sockets vs. Data Queues

[Evan Harris <spanner@xxxxxxxxxx>]

Hi Tom and Scott

I'm really having trouble trying to picture how this could be easier if the
server process is on the same machine as the proposed socket. Can someone
enlighten me how this would be less work ?

I've used data queues many times to control server processes but if there's
a better way I'm all ears.

BTW Scott, the two way communication - I find it easier to just have a
queue for each process. Part of the information a job sends to the server
on it's queue is the name of the queue to respond on. Obviously this takes
some planning up front but works pretty well. Apologies if you already had
this figured; I'll be surprised if you hadn't ! :)
