Closed choidi closed 9 months ago

choidi commented 1 year ago

When the requests with the same session id comes, the RedisSessionInterface save_session function set value without lock or compare with the original session value, it may cause the latest modified value is covererd by the old one. It is not need to update redis value and set cookie in every response.

@choidi Can you explain how you would change the code, or give a snippet? Are you refering to permanent session?
