I'm trying to load XP drivers for in "Manage Broker" in iManage, but
when I "Add from file" I get a long delay and then the error:

Bad Gateway! The proxy server recieved and invalid response from an
upstream server

Error 502, 192.168.1.11
(Date and Time)
Apache
/2.0.59 (NETWARE)mod_jk/1.2.15


Any ideas on how I could get around this?

Thanks
Jim
