For MVC, make sure the web.config has below configuration.

I was facing the same issue and tried every option mentioned in the above answers. Finally found that the issue was that we had marked session cookie as secure in our project but were running it with http If the server has not been setup for SSL and you try to mark the cookie secure, a new session will be generated for each request. So finally enabling back https fixed it for me.

Answer 3

I believe your session in the web.config is being reset (getting a new SessionID for each postback)

You could try to debug this by putting the SessionID somewhere on the page (for testing) with

HttpContext.Current.Session.SessionID

This did happen on one of my websites and all i had to do was go into IIS and resave the SessionState Panel

Answer 4

Check your web.config, maybe you have this tag

<httpCookies requireSSL="true" />

If it so, remove it.

Answer 5

You need to update web.config as mention below :

<httpCookies requireSSL="false" />

Answer 6

Just go to your web.config file and edit your sessionstate tag. Set requiressl to false from true.
