title: Event Handlers Might Not Be Not Raised in a Default Document in IIS 7 or IIS 7.5 Integrated Mode?
body: <p>After pulling my hair out for the last three days in my first non-upgraded ASP.NET 4.0 Web Application, I stumble across this post explaining it all.</p>
  
  <p><a href="http://jai-on-asp.blogspot.com/2010/06/changes-and-differences-between-aspnet.html" rel="noreferrer">http://jai-on-asp.blogspot.com/2010/06/changes-and-differences-between-aspnet.html</a> under the section labeled: <strong>Event Handlers Might Not Be Not Raised in a Default Document in IIS 7 or IIS 7.5 Integrated Mode</strong></p>
  
  <p>Apparently, an asp.net page at this address: <a href="http://www.mydomain.com/" rel="noreferrer">http://www.mydomain.com/</a>  will not post back to itself without explicitly adding action="default.aspx" in the <code>&lt;form</code>> tag.</p>
  
  <p>Well, what happens when you are using a Master Page (where the <code>&lt;form</code>> tag is location when using Master Pages)?</p>
  
  <p>How do I get my default.aspx pages to postback to themselves in .NET 4.0 using Master Pages?</p>
