Subject Session Affinity after Graceful Apache restart? [was Re: Adding working dynamically with mod_jk status?]
Date Tue, 07 Jun 2005 17:09:01 GMT

Hi,

I've been asking some more questions about restarts on the Apache list, and
was redirected back here...

Does anyone know (David, Mladen?) what will happen to session affinity is
this situation?

ie with Apache in front of several tomcats using mod_jk, when Apache is
restarted "gracefully" using "apache -k restart" (Windows) will session
affinity be preserved across the restart?  ie will browsers with a session
open with a particular Tomcat continue being directed to that particular
Tomcat after the restart?

cheers,

David

Have you seen if a graceful restart of Apache works for you?  Graceful
restarts of Apache have worked for me in the past to add new workers
without dropping requests.
