Thanks so much for your help Liviu. In the end, I used the $shv()
approach you suggested. It worked like a dream! :-)
In opensips.cfg:
loadmodule "cfgutils.so"
modparam("cfgutils", "shvset", "cacheValid=i:0")
route{
if ($shv(cacheValid) == 0) {
Glad it worked! Depending on the volume of traffic flowing through your
instance, maybe it would be better to perform the "is cache valid" check
within a timer route [1] at a frequency of your choosing, rather than on
each SIP request.
