# Automatically shortens URLs seen, using the redirx service.

# - replace long urls on output, too

@ redirx.host = [redirx.com]
@ redirx.port = 5313

# if response not received within this many seconds, assume server is
# dead

# suppress original non-changed output?
# must reload script after changing this!
