[SR-Users] In memory ISP Info

[Daniel-Constantin Mierla]

Hello,

use:

modparam("htable", "htable",
"isp=>size=8;dbtable=isp;cols=ispname,ispip,ispuser,ipsprefix,ispprefix")

then you have the $sht(ispname) with value corresponding to
"ispip,ispuser,ipsprefix,ispprefix" and then you can use {s.select,,0}
to get ispname value, then {s.select,,1} to get ispip value, etc...

An alternative would be to keep only two columns in database, one (the
key) with ispname and the second (the value) all fields serialized in a
json document and you use jansson to parse them in config.

Cheers,
Daniel
