ASP.NET 4.0 Active MarkUp v/s Passive Markup

ASP.NET 4.0 gives us two main flavor of programming style. Active Markup and Passive Markup.
ohh..!! what is this new terminology Active Markup and Passive Mark Markup.. ?!!!. This term you never find on msdn or any Microsoft Evangelist's blog or book. this is new term coin by me for ASP.NET webform and ASP.NET MVC..



v/s

why I have used this new term to make things more messy...!!! ...well I have used this terms to make things much easier to understand ASP.NET MVC if one has knowledge of ASP.NET Webform programming and page life cycle.
So lets go back to our understanding of ASP.NET Page and it's Life Cycle.
normally in ASP.NET we have page name .aspx and their code behind .aspx.cs or .aspx.vb . In asp.net page we usually write html markup and server control markup like <asp:bla runat="server" >...</asp:bla> ...... in sort .aspx page is nothing but the a markup page.
Similarly in MVC we also have .aspx page and those are called view pages and in those .aspx page we wrote html (means markup code) and wrote some binding to those html with model entity and if we are using razor view engine then we may have .chtml file which is again have html and their binding with model entity. means view are nothing but the markup pages. hence in both programming framework we have markup pages where we write our UI as markup..
But, both framework while request is processed, they handled Markup in different way to generate response . in WebForm markup page comes first to process while in MVC markup page come at last to process hence webform is ActiveMarkup and MVC is PassiveMarkup.

ASP.NET Webform.
when user request http://somedomain.com/somepage.aspx then IIS server will search somepage.aspx file in virtual directory where your webproject is placed. means request 1st comes to your aspx page then from page directive it will find out which page class(code behind) need to execute. hence your markup page process request before the their cod behind (actully this code behind reside(after compiling and publishing) in .dll file and this dll file reside in bin ) so I called as Active Markup page framework.

ASP.NET MVC

when user request http://somedomail.com/home/about then as per configuration of routing table Server search a class named HomeControler(derive from controller class) of dll reside in bin. and inside that it will serach public function name about and handover this request to this function. now this function will process this request and then call approprivate view(markup) file and finally generate response. so markup page come last so I called as Passive Markup page framework.
