Using ASP.Net MVC 4/C# Datacache object is confusing users

So I am new to the whole datacache thing. I am building an app for a client who has potential to grow substantially so I am using the datacache instead of Session variables so that I can have multiple servers.

I have been in development mode and this has worked just fine, but it has just been me.

Now we are testing and completely new people on a computer that have never been to the site before are being recognized as another user somehow...

I do use cookies to remember a user, but these guys are coming in for the first time so that can't be it. Never had this problem with Session variables so I must be doing something wrong with the datacache.

Why does the datacache confuse the users? How do I prevent this?

Thanks! David

cache = server level, session = user level. Your server is saving the cache data and passing it along to the users. If you have intentions of having multiple users connected, and storing separate data for each, sessions is actually the correct way to do it.

As for performance, yes there will be a slight performance hit, but it shouldn't be too drastic unless you've got a massive amount of users hitting the site at one time or you're storing huge amounts of data to the session.

You need to use Session to store a logged in users credentials and other session specific information. Datacache is used to store application wide data that can be quickly accessed, things like xml files used on the website or perhaps a dataset used by anyone on the website. Session is a unique id and "thread" for each user for their specific user name and all other information related to their logged in id.
