If I get the same object from two different sessions and make no changes object.Equals(sameobject) still equals false. What I want to do is store an object in the users asp.net session and then several requests later be able to let the user know if they have made any changes that they need to save. What's the best way to go about implementing this?

Thanks

It depends on how you are implementing .Equals. Personally, I favor a 'Business key' comparison instead of an 'Identity key' comparison for exactly this kind of scenario...and because it is recommended in the Hibernate in Action book.
So instead of comparing based on the identifier value (id) you'd compare the immutable values in your class (perhaps 'name' or 'social security number').
Of course, this presumes some immutability exists in your class...which is usually the case or perhaps pointing to a design decision left undone.

The only other alternative I could think would be to reattach the object to the Session and then let NHib check the IsDirty state.

In my WinForms app, I use the ISession.IsDirty() method to see if a session has changes that have not been saved to the database.

However, this checks the entire session! So it doesn't tell me if a specific object has changes, only if the session has changes.
