APM Multi-domain configuration, log off page redirect

OK, I got this figured out. Since this was a VS for OWA, there already is an iRule that does the redirecting, I just had to modify it slightly. Look for the line below with "https://portal.company.com/" in it.

when RULE_INIT {
    set static::cookie_sessionid [format "sessionid=null; path=/; Expires=Thurs, 01-Jan-1970 00:00:00 GMT;"]
    set static::cookie_cadata [format "cadata=null; path=/; Expires=Thurs, 01-Jan-1970 00:00:00 GMT;"]
    set static::cookie_usercontext [format "UserContext=null; path=/; Expires=Thurs, 01-Jan-1970 00:00:00 GMT;"]
}

when ACCESS_SESSION_STARTED {
    if { [string tolower [HTTP::uri]] contains "ua=0" } {
        ACCESS::session remove
    }
}

when ACCESS_ACL_ALLOWED {
    set apm_mrhsession [HTTP::cookie value "MRHSession"]
    if { [table lookup $apm_mrhsession] == "EXCHANGE_LOGOUT" } {
        ACCESS::session remove
        table delete $apm_mrhsession
    }
}

when HTTP_REQUEST {
    set isset 0
    if {[string tolower [HTTP::uri]] starts_with "/owa" } {
        if {[string tolower [HTTP::uri]] contains "logoff" } {
            ACCESS::session remove
            HTTP::respond 302 Location "https://portal.company.com/vdesk/hangup.php3" "Set-Cookie" $static::cookie_sessionid "Set-Cookie" 

$static::cookie_cadata "Set-Cookie" $static::cookie_usercontext
        } else {
            if { [string tolower [HTTP::uri]] contains "ua=0" } {
                set mrhsession [HTTP::cookie value "MRHSession"]
                set isset 1
            }
        }
    }
}
when HTTP_RESPONSE {
    if { $isset == 1 } {
        if { $mrhsession != "" && [HTTP::status] == 440 } {
            table set $apm_mrhsession "EXCHANGE_LOGOUT"
            return
        }
    }
}
