Michael: I've been focusing on finding paid work, however, the Tomcat side of things is pretty much done. What remains is:
- Completion of Valve (that notifies session manager when a request is complete). Craig tells me the code for this needs a little work, and I'm waiting for him to provide some more details about this. - Session ID mangling. - Apache Connector changes - No action has occurred on this, I'm dependant on someone else making these changes. I'm hoping that Costin will do this when he's done with the 4.02 release work - Final integration and testing Note. The 'session' locking feature that I added is probably not necessary as long as server / session affinity is in place. This should either be disabled or made 'optional'. Lastly, I got to thinking that it should be possible to have a Tomcat only load balancing / fail-over solution. What's needed is a Tomcat front-end on which is deployed a new servlet that would do a simple round-robin load-balancing, but when jsessionid's are present, route them to the session host only, unless the session host doesn't respond, in which case it should be re-routed to another available instance. So, I started writing some code to do this, and then got side-tracked looking for work again. Nasty things, bills. I'm still plugging away, however, Tom ----- Original Message ----- From: "Michael Remme" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Wednesday, January 09, 2002 12:04 AM Subject: AW: tom4 session and loadbalancing / Distributed Session Management | Hi Tom, | | anything new about this theme? | | Best, Michael | | > -----Ursprüngliche Nachricht----- | > Von: Tom Drake [mailto:[EMAIL PROTECTED]] | > Gesendet: Sonntag, 16.
