# Session is be stored on disk. Save the session on the local disk.
Session = web. session. Session (app, web. session. DiskStore ('session '),
Initializer = {'Count': 0 })

Class count:
Def GET (self ):
Session. count + = 1
Return str (session. count)
Class reset:
Def GET (self ):
Session. kill ()
Return ""
If _ name _ = "_ main __":
App. run ()

Second, save the session information of the browser in mysql.

The table structure is as follows:
