iRule Not Firing after APM policy completes

Hi,

I'm struggling to understand what is going on here.  Basically, we have an iRule on a HTTPS virtual server that takes the URI and presents a corresponding iFile.  This works perfectly but when I apply an APM policy to the configuration, the iFile never gets displayed.  Without the APM policy, we use the HTTP_REQUEST event but we can't use that since it fires before the APM policy can be started.  If we use ACCESS_ACL_ALLOWED, then the APM policy works but no content is diplayed and we see ERR_CONNECTION_RESET.

I've logged everything and the session.server.landinguri has the correct value for the URI but no content.  We're using the following in the iRule:

set uri [ACCESS::session data get "session.server.landinguri"]
switch -glob $uri {
     "/mylandinguri.html" { HTTP::respond 200 content [ifile get "mainpage"] }
}

Not sure what other events I need to do this.  The APM policy is on the same virtual server as the iRule.  The APM policy only displays a messsage box that a user can accept so no AD Auth or any other objects being used.

Any help is greatly appreciated.
