I made IIS beg for mercy (HTTP/1.1 500 Server Too Busy). -Galt >===== Original Message From [EMAIL PROTECTED] ===== >Hello, > >In version 2.2 core, I used to have something like this >to instantly poll a TCP connection if it has any data: > >wait [0 conn] > >If there is no data, then none was returned; otherwise >there is data on the connection. > >I haven't been able to figure out the right thing to do >in 2.3 core; 'wait [0 conn]' always returned none even >if there is data available. > >Any ideas on how to do it in 2.3? > >-Alfred
