HTTP JVM: com.ibm.xsp.acl.RedirectSignal - What does it imply?

After upgrading the Domino server to 8.5.2, we've occasionally been getting entries like these in log.nsf on the server:

04.10.2010 14:07:39 HTTP JVM: com.ibm.xsp.acl.RedirectSignal
04.10.2010 14:07:50 HTTP JVM: com.ibm.xsp.acl.RedirectSignal
04.10.2010 14:09:08 HTTP JVM: com.ibm.xsp.acl.RedirectSignal

I've been trying to ask Google for help on this, but without any luck. In fact, if you google the phrase "com.ibm.xsp.acl.RedirectSignal", you get a single hit (!): http://www.timtripcony.com/xpages_ext_api_javadoc/serialized-form.html

Does anyone of you Lotus Notes experts out there have some more info on this topic?

Might not be a big problem, but I'm a bit paranoid when it comes to entries in the log.nsf... :-)

Update: I've also created a topic at the Notes 8.5 forum over at lotus.com - LINK


  1. Okey, so it seems like this log entry occurs when you have code line like this:
    return context.redirectToPage("page",false);

    Why it has started showing up in the logs now, after upgrading to 8.5.2, is a different question...

  2. We get the same message in the server console.
    The XPage's beforeRenderResponse event has this code (in a conditional statement):

  3. @Helge: Thanks for confirming that you guys see it as well!
    We've contacted IBM to see if there's a way to stop these log entries, as it's kinda flooding our logs... :-) Will update here when we get a response!

  4. @Rasmus: Did you get any response from IBM or have you figured out how to avoid these log entries?

  5. @Helge: No answer from IBM on how to avoid it in the logs, but they have said that it should be possible to do so in 8.5.3. Will be a while before we upgrade to that version, sp hoping for another solution...

  7. add the code to afterpageload events


  8. If you use navigation rules you will avoid getting the redirectsignal errors
