--- Comment #2 from Archie Cobbs <arc...@dellroad.org> ---
Thanks for the clarification.
What would be the appropriate next step then? Would getting this to work
constitute a feature request for Apache httpd, or Tomcat, or both?
FYI, the upgrade request does pass through to Tomcat via AJP and Tomcat does
respond (see packet trace below)... is this just accidental?
Thanks for helping me understand what is going on here.
