ASP.NET-4 IIS7.5 web.config serverRuntime element

Question

Whenever I add this line to my web.config in the system.webServer section:

<serverRuntime />

With our without properties, IIS 7.5 just serves up a blank page instead of the website. I created a new empty Web Application using IIS and added the line to the web.config; blank page.

What am I doing wrong?

Answer 1

So you are actually adding this to your web config?

<location path="Default Web Site">
   <system.webServer>
      <serverRuntime enabled="true"
         frequentHitThreshold="1"
         frequentHitTimePeriod="00:00:20" />
   </system.webServer>
</location>

There are several important things to bear in mind...

1. That you are running IIS7 in integrated mode, not classic mode.
2. That you have the enabled="true" attribute set on serverRuntime
