Variables are not shared between HTTP events and ACCESS events.

The original landing uri is saved as a session variable, 

session.server.landinguri

So from any APM event you can use 

[ACCESS::session data get session.server.landinguri]
you will get the original URI. Since the policy runs at the start of a connection, this variable is probably what you are looking for.

Having said that, he best way to pass the value of a variable between APM and LTM events is to stuff it into the APM policy session variable data structure. 

when CLIENT_ACCEPTED {
    ACCESS::restrict_irule_events disable
}
when HTTP_REQUEST {
   ACCESS::session data set session.http_uri [HTTP::uri]
}
when ACCESS_POLICY_AGENT_EVENT {
    if { [ACCESS::policy agent_id] eq "do_it_now_or_never" } {
        set uri [ACCESS::session data get session.http_uri]
    }
}

HTH.

    I should clarify some things: The string "do_it_now_or_never" is a label you enter in the VPE to identify the location within the flow chart where you called the iRule Event from. This is yours to define. Stuffing and retrieving a value is session variables data structure is done via the commands: "ACCESS::session data set" and "ACCESS::session data get".
