[OpenSIPS-Users] Issues with registration proxy

[Patrick Wakano]

Hi,
I think cached attributes are like global variables, unique and valid in
the whole Opensips execution. You can store them and fetch at any time
regardless the message you are handling. So, as you suspect, the logic of
the piece of code you showed will store for 1200s the value in cache for
the first request that comes in. During this lifetime, any other subsequent
request won't cause an update in its value. After 1200s the cached
attribute will be deleted and the whole logic will repeat in the next
request it receives.
Not sure why you tried to use the cache to store your domain, maybe because
you need it later in your dialog. If this is the case rethink your logic
and use dialog variables.
