In 1.5 (svn.r2171 - package from SuSE Build Service for SLES10 and the same in svn.r2419), an undocumented option is hardcoded into the sourcecode.
See: configfile.c, s->max_connection_idle = 360;
It took me hours to find out, why POST requests stopped after 6 minutes, but worked fine with the 1.4.x Versions.
It would be great to put this option into the lighttpd.conf and/or set the default value higher (I'm using one hour right now).
