Client-id is nil in version 1.17.0

[fsrc]

I have the following minimal project that starts a server on port 3000. When I request it in Google Chrome like so http://localhost:3000/chsk?client-id=234234 I get the following result +[[:chsk/handshake [:taoensso.sente/nil-uid nil]]].

I had the same problem running DavidVujic/sente-with-reagent-and-re-frame referenced in the README.md file.

@fsrc Hi Frederik, Sente uses two different identification concepts:

1. Client-ids (cids) that refer to specific connections (browser tabs, devices, etc.).
2. User-ids (uids) that refer to a logical user with >= 0 associated client-ids.

I get the following result +[[:chsk/handshake [:taoensso.sente/nil-uid nil]]]

This message indicates that the user-id ([2]) is nil, which is normal and expected if no user-id has been manually assigned. The message doesn't indicate anything about the absence of a client-id ([1]).

The reference example project shows how the user-id can be assigned and used.

Hope that helps! Cheers :-)

I should add - Sente v1.18 is scheduled for release around end of April, and I'm hoping to include some improved documentation - including a new Wiki which will include a discussion of the above identifiers.

Ok, I see. Thanks for the fast reply!
