IfModule itk.c ignored even if I'm running Apache itk

Question

I'm running itk as Apache MPM.

In order to prevent error in case I need to change the MPM in the future, I set

    <IfModule itk.c>
        AssignUserID user group
    </IfModule>

but I found that it gets ignored. In fact, if I add a WTF like and run rcapache2 configtest it returns me Syntax OK

    <IfModule itk.c>
        AssignUserID user group
        WTF ##doesn't throw error
    </IfModule>

By the way, /etc/sysconfig/apache2 shows APACHE_MPM="itk"

How do I check if I'm running itk or not?

EDIT: If I remove the ifmodule and restart I get

Invalid command 'WTF', perhaps misspelled or defined by a module not included in the server configuration

If it throws an error when IfModule is commented out, then Apache doesn't think the itk.c module is actually loaded (so its not parsing the contents of the conditional statement).

But that is not to say that the itk module isn't actually being loaded. Otherwise, you would likely also have a an exception being thrown for AssignUserID too.

This isn't the first time I've come across Apache mis-reading the .c/.h files and thinking a module isn't loaded, when it actually is.

To know if its actually running - just check your vhost user in top/ps

Eg. ps axu | grep -E '(apache|httpd)'
