Specifying read-only session in ASP.NET MVC

Question

Is there any way to specify that a given Controller or Action uses Session state in a read-only manner? In "old" ASP.NET we used to do something like this:

<%@ Page EnableSessionState="ReadOnly" %>

Is there an ASP.NET MVC equivalent? I'm looking to allow my application to serve multiple requests from the same client simultaneously, and turning off session completely is -not- an option in my case.

Answer 1

In Asp.Net MVC3 there is now a SessionStateAttribute that you can decorate your Controller with to force all actions into Read-Write, Read-only, or No session mode.

A similar question was asked here: Disable Session state per-request in ASP.Net MVC

The accepted answer deals with creating a custom route handler that ultimately skips binding to the session. This doesn't exactly answer your question (which is how to declare multiple actions to use readonly session access), but it seemed relevant enough to mention.
