[Orca-users] Re: orca w/ different hosts/orcallator data.

[Blair Zajac]

Brian,

This is a bug in the current version of Orca.  I'm working on a newly
designed version of Orca that will be handle this issue and many more
data types of the kind, including something like

# URL              First byte time     Total time
www.geocities.com  1.0                 2.0
www.yahoo.com      1.1                 2.0

In the meantime, I do not have a fix for this, but if I do, then I
will send one out.  For now, I would separate the hosts that have
and do not have web servers on them.
