# mirror(): Its purpose is to deal with proxy authentication. When we

# LWP::UserAgent. LWP::UserAgent will then call
# $self->get_basic_credentials or some equivalent and this will be
# $self->dispatched to our own get_basic_credentials method.

# Our own get_basic_credentials sets $USER and $PASSWD, two globals.

# 407 stands for HTTP_PROXY_AUTHENTICATION_REQUIRED. Which means
# although we have gone through our get_basic_credentials, the proxy
# server refuses to connect. This could be a case where the username or
# password has changed in the meantime, so I'm trying once again without
# $USER and $PASSWD to give the get_basic_credentials routine another
# chance to set $USER and $PASSWD.
