Hi, Jade,
I just checked posting there, it's already done. Thanks for prompting me to check. sample-config.tcl[1] is only set to use nsssl not nsopenssl, and nsd.tcl[2] in the nsopenssl directory already has it set true. Not to mention that searching the aolserver listserv archives shows that they also recommend this value to be always set true (search for "session cache").
I'll post a change in the bugtracker.
