.net - Exclude certain pages from using a HTTPModule

Question

Is there a good way to exclude certain pages from using a HTTP module?

I have an application that uses a custom HTTP module to validate a session. The HTTPModule is set up like this in web config:

<system.web>
  <!-- ... -->
  <httpModules>
    <add name="SessionValidationModule"
       type="SessionValidationModule, SomeNamespace" />
  </httpModules>
</system.web>

To exclude the module from the page, I tried doing this (without success):

<location path="ToBeExcluded">
  <system.web>
    <!-- ... -->
    <httpModules>
      <remove name="SessionValidationModule" />
    </httpModules>
  </system.web>
</location>

Any thoughts?

HttpModules attach to the ASP.NET request processing pipeline itself. The httpModule itself must take care of figuring out which requests it wants to act on and which requests it wants to ignore.

This can, for example, be achieved by looking at the context.Request.Path property.
