[dancer-users] authentication with tokens

Tere! I am looking for solution how handle requests simply and securely for RESTful web-service. Theoretically it should look like this: 1. on first approach client should log in with usual credentials (like username and password) 2. system generates unique token and returns it to client 3. on every subsequent request client uses token to identify itself 4. when token ages, client starts from first point again I tried some queries on metacpan and google, but did not find nothing involving Dancer and even Perl as whole. Do you have some hints for me, where to look? To implement it with one table seems not too hard, but to have something battleproofed and abstracted out would be appreciated. TIA, -- Wbr, Kõike hääd, Gunnar
