title: ASP.NET MVC - Is IsPostBack still here?
body: <p>I know, I know, I know.  I shouldn't be doing webforms inside of MVC, I completely agree.  But, the people who sign my paycheck will not approve a complete conversion of our site to MVC right now.  So I am taking incremental steps, page by page, to convert them over while adding new features in MVC.</p>
  
  <p>So my question is how can I access the IsPostBack property from a controller?</p>
  
  <p><strong>Edit:</strong>  To further clarify, I have a webform user control on my mvc master page which can initiate postbacks.  I'm trying to identify these postbacks verses an mvc post.  At this point I think I am going to just check the request form keys for a "__viewstate" key and if its found treat it as a postback.</p>
