Blank page on IIS 7

[mercede75]

Hi,

We have created an application using Ext.NET 1.1 tested on IIS6 (Windows 2003 SP2). However our first deployment failed on IIS7 (Windows 2008 R2). The pages show blank. The regular HTML stuff was okay but the EXT stuff was just not there. The page source did contain the Ext.NET stuff but it just did not appear in browser.

We tried it on

• IE9
• Chrome
• FireFox
• Opera

Every browser behaved the same way. After researching sometime, changing the DefaultApplicationPool to Classic .NET application pool and there it was.... working fine.

The problem is solved but why the Ext.NET run in the Default Application pool. I used Fiddler and found this:

#	Result	Protocol	Host	URL	Body	Caching	Content-Type	Process

With Classic .NET pool everything is returned with code 200. Did we make some mistake in Web.Config file or some permissions are required? Is it some bug in Ext.NET?

I'm curious to know.
