[Zope] virtual hosting and error messages

[ed colmar]

Hey friends!

    I've got a bunch of hosts running on one of my zope servers.  Apache,
and SiteAccess made it happen quickly and easily.

    I have a question regarding a unique error message I've been seeing.

    When filling out a form, I have a value that is being passed to zope as
"cost:int"

    The form works fine when filled out correctly, but returns an error if
this field is left blank.  Now, this is the behaviour that I want, but I'm
trying to track down where the error page comes from.  This is different
than "standard_error", and the really peculiar thing about it is that it
pulls in the "standard_html" header and footer from the root folder, which
happens to be a completely different host.

    Needless to say it is very confusing to have an error pop up on a forign
looking page.  Anyone know where this file is? or how I can trick aquisition
into letting me use the standard_header and footer from the site that
generated the error?

    thanks so much!
