ASP.NET 1.1 on IIS 7 using handler mappings

The problem I was experiencing was that I could not set any custom handler mappings in IIS 7 because it would add a <system.webServer> tag to the web.config of my application. This would crash my asp.net 1.1 app because it doesn't understand the tag. So there I was wanting to use the new IIS 7 and not being able to set any custom handler mappings because they would be stored in the web.config of my application.

But there is a solution to this problem! You need to add a line to your machine.config in order for asp.net to ignore the above tag.

1. Go to the machine.config file for your .net 1.1 framework (C:\Windows\Microsoft.NET\Framework\v1.1.4322\CONFIG\machine.config)

2. Add the following line to it just above the </configSections> closing tag

    <section name="system.webServer" type="System.Configuration.IgnoreSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

Et voila, there you go. The best of both worlds, if you need to debug 1.1 apps anyway.
