I'm hoping to store several gateway IP's in a hash table using HTable,
then grab one of them randomly. Does anyone have a recommendation as to
how this can be done, or perhaps a better way to do it? I chose HTable
because a) I want to reload the values every x minutes and b) I'm using
it for other purposes.

add in htable several keys:
- "gateway[x]" - where x is 0 to the number of gateways
- "gateway::size" - where to store the number of gateways
Then use the cfgutils module and get your gateway with:
$var(x) = $RANDOM % $sht(gateway::size);
$var(gwip) = $sht(gateway[$var(x)]);
FYI - although you may know - dispatcher has an algorithm for random
selection of destination.
Cheers,
Daniel

Very cool Daniel . . . thanks for the quick response. There is one
question, however; What I'm hoping to do is keep x number of gateways in
the hash table, letting them expire after 10 minutes. If the system
finds that the entries are gone (e.g. $sht(a=>gateway) == null ) then it
would reload the table. My reason for doing this is in case I need to
take one of the gateways out or add another.
Any thoughts, or am I missing something?
