Handling MVC Session for every page

In fairly new to MVC and I would like to use a session. I have a base controller and all my other controller inherit from my base. I need the session checked every time a page is hit.

What is the best开发者_如何学编程 way to go about this?

My session will need to store an id to be able to build the pages correctly. If the session doesn't have the ID I need to look up the information in DB. I don't want to use cache because IDs could be different for different users.

I recommend going the cache route.

Create a class called 'CacheHelper' and within it, a method called 'GetId()' In the GetId() method, setup a Dictionary object to store your values and use the username as the key. Each time you call GetId, check to see if the Key exists in your dictionary

myDictionary.ContainsKey(username);

If not, look it up in the database, add it to the dictionary, then resave it to cache.
