How do you prevent the IIS default site web.config file being inherited by virtual directories?

Question

I have the following code in a web.config file of the default IIS site.

<httpModules>
    <add type="MDL.BexWebControls.Charts.ChartStreamHandler,Charts" name="ChartStreamHandler"/>
</httpModules>

Then when I setup and browse to a virtual directory I get this error

Could not load file or assembly 'Charts' or one of its dependencies. The system cannot find the file specified.

The virtual directory is inheriting the modules from the default web.config.

How do you stop this inheritance?

Answer 1

I've found the answer. Wrap the HttpModule section in location tags and set the inheritInChildApplications attribute to false.

<location path="." inheritInChildApplications="false">
  <system.web>
    <httpModules>
      <add type="MDL.BexWebControls.Charts.ChartStreamHandler,Charts" name="ChartStreamHandler"/>
    </httpModules>
  </system.web>
</location>

Now any virtual directories will not inherit the settings in this location section.

@GateKiller This isn't another website, its a virtual directory so inheritance does occur.

@petrich I've had hit and miss results using <remove />. I have to remember to add it to every virtual directory which is a pain.

Answer 2

Add the following to the virtual directory's web.config file:

<httpModules>
    <remove name="ChartStreamHandler"/>
</httpModules>
