From a bit of experimentation today, the passthru servlet seems to check if the hostname portion of the servlet request matches the hostname portion of the _xslsrc parameter. If they differ, and the servlet parameter in web.xml is set to no (default):
allowremote
no
then you get this error. I can’t see why you are getting this error because both hostnames appear to be “localhost”. But you could try setting allowremote to yes in web.xml and see if it bypasses the problem for now.
