[BUG] Session.IsNew() always returns false if I use a db

[reedchan7]

Describe the bug
Session.IsNew() always returns false if I use a db.

• Iris version: v12.1.8

To Reproduce
A new HTTP request comes in with an empty cookie, the Start function is called by the middleware session.Handler(), then I found that s.provider.db.Len(sid) was 0 after a new sid was created, but after the line 87 invoked: sess := s.provider.Init(sid, s.config.Expires), s.provider.db.Len(sid) returns 1. so, session.IsNew() will always return false, even though it is a clean、new HTTP request.

Shall we swap the line 87 and 88 ?

Expected behavior
A new HTTP request comes in and session.IsNew() returns true correctly.

Hello @juan-chan, nice report. This is fixed with a commit to the master main branch.

This happened to redis and badger (boltdb is fine) because they fetching per prefix, which included the session id 'bucket/item' itself.
