Hello,
indeed, as Alex said, it is just a stylistic choice, the main purpose would be to use a character that is not allowed in variable names to mark the end of the variable (to avoid the use of ( ) to surround the name of the variable). Anyhow, it is not needed to use any static string as part of the key, can be only a variable, like $sht(x=>$ru); or can be only a static string, like $sht(x=>abc); or many variables and static strings: $sht(x=>$si::$rU::count). The :: is not seen as a special delimiter or anything similar, is pure static string from htable key point of view.
The choice of :: has probably relation with its usage in other languages like C++ to refer to (static) fields/methods. For me is also more friendly from human reading point of view, quite (white-)spacious, allowing to spot quickly the tokens composing the key.
Cheers, Daniel

Hi,
This is an arbitrary stylistic choice that is just consistently followed in the documentation examples, likely because it was written by the same person, or imitated by others. The colons are not required.

Hey everyone,
Whenever I read documentation for htable usage, and other examples of other scripts in Kamailio, htable keys are typically named:
something::something
Examples are: $au::auth_count, $ci::srcip, join::$rU
Why are there two colons (as opposed to a | )? Is this just a standard semantic thing in Kamailio? Is there something about that double character that’s unusual and easy to parse with SIP values? Or is it just what people do, and that’s a good choice to continue for all other Kamailio script writers to have understanding?
Any insight would be appreciated.
Thanks!
