if session.setMaxInactiveInterval(0) , also same as <session-timeout> 0 </sesion-timeout> this means never timeout or timeout immediately? from the HFSJ page 247, it says it is timeout IMMEDIATELY, but i find another book say it is never timeout...
for <session timout> if its 0 or <0 means session never expires for setMaxInt..(int) if its only <0 means session never expires, if its 0 here ...i guess its timeout immediately.
