I successfully mirrored one of my company's sites.
But when I followed the same steps to mirror a related site it failed to
mirror.
The site (http://www.culinacareers.co.uk/) looks fine in my browsers (chrome,
IE).
The error in the log is
12:50:26	Error: 	"Proxy Authentication Required" (407) at link
www.culinacareers.co.uk/ (from primary/primary)

12:50:26	Warning: 	No data seems to have been transferred during this session!
: restoring previous one!

Although our proxy has never yet required me to log in, I tried following the
instructions for adding authentication. The same problem existed with or
without  authentication added.
Any suggestions?
