RE: Formation of ACKs?

Hi Marcello,

I'm not matching them as you suggest, so that might very
well be the case. I'll try it, thanks!

Hi,
are you sure that Openser is processing the ACK packet with
t_relay() to 
match it against existing transaction?
This is the same issue i had 2 days ago and solved putting
a:

        if (method=="CANCEL" ||
method=="ACK") {
                route(1);
                return;
       }

in my main routing block. The route[1] is route block that
process 
request with t_relay().
Before i didn't put the ACK in the if clause but only the
CANCEL.
Hope to helped,
Bye,
Marcello
