Exclude certain pages from using a HTTPModule

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?
