===============================================================================
SPEC has determined that this result was not in compilance with the
SPECweb99 run and reporting rules. Specifically, the result did not meet
the 3 month availability requirement in the SPECweb99 run rules due to a
change in availability of the HP 9000 Model A500. Results for the same
hardware and software configuration have been submitted to SPEC that
address the availability issue.

cache_stat_expire 864000 (check for file updates daily)
cache_flush_interval 864000 (flush cached files daily)
sendfile yes (use the HP-UX sendfile system call)
sendfile_reservefd 30001 (keep lots of descriptors available for sendfile)
sendfile_minsize 0 (no file is too small for a sendfile)
listen_queue_size 8192 (allow more connections to queue)
cbuff_size 1048576 (use large buffer for cgi interface)
timeout 7200 (don't give up on a client easily)
