how to prevent inheritance for web.config file for "configSections"?

Question

I have following in my parent web applications config file

<configuration>

<sectionGroup name="testmodule">
              <section name="testmodule" type="RewriteModule.RewriteModuleSectionHandler, RewriteModule"/>
</sectionGroup>

........ i want to prevent child subfolders from inheriting this config section where should i put <location path="." inheritInChildApplications="false">, since config sections should be first child element of configuration file

Answer 1

This has been answered a couple of times on SO, but incorrectly in my opinion.

The docs, are pretty clear (1)(2):

The following example shows how to use this attribute in a configuration file to specify that the settings defined in the location element for the root of a Web site should not be inherited by child applications:

The InheritInChildApplications property applies only to location-specific configuration settings.

To answer your question, this should suffice:

<configuration>
...
<sectionGroup name="testmodule">
    <section name="testmodule" type="RewriteModule.RewriteModuleSectionHandler, RewriteModule"/>
</sectionGroup>
...
<location path="." inheritInChildApplications="false">
    <testModule>
    ....
    </testModule>
</location>

Answer 2

Seems to be no solution for this currently, should avoid using conflicting section groups in web.config file.
