title: Storing 'session values' in MS MVC3
body: <p>I'm getting started in MVC3 with a jquery/js driven front end.  I realise that the paradigm of MVC is not to rely much on the concept of session variables and the like, instead using the actions and controllers to drive the user experience.  I have the situation below, what's the proper way to do it?</p>
  
  <p>a) I have a little menu with a set of 'select exhibit' options - show summary, show user details etc.  Clicking one calls a controller (lets say 'rendersummary' or 'renderuserdetails') which returns a partialview back a certain div on my page.</p>
  
  <p>b) I have a separate 'filters' panel, which lets you select how many records to include, etc.  In that, I have an 'apply' button.  When you click apply, I'd like it to re-execute the last action again (eg rendersummary) but now using the new filter settings.</p>
  
  <p>I recall you could use HTMLRoutings or something to see what the current action/args are, but am not sure how you'd do this for the most recent partialview.</p>
  
  <p>Any thoughts?</p>
  
  <p>Thanks!</p>
