Re: setting variables with a pluging

[Mark . Burgess]

THe reason seems to be that the variable expansion was a few lines
too late in the code to work as it was intended. However, if you
just want to choose a server based on IP address, why don't you
do something like this:

copy:

 128_38_89::

  /src1 dest=/dest server=server1

 128_39_74||192_0_2_1::

  /src2 dest=dest server=2


Meanwhile, I'll fix the otherthing in the coming weeks.
best,
Mark
