that's a call that each individual has to make. if you're uncomfortable with google knowing your intranets title tags and urls then don't. the guy is looking for potential solutions not explantions of why he can't or shoulndt do something.

Yup, that and Squid 3's "not production quality" status makes the whole Squid/ESI thing a total non-starter, which is a shame... ...but I do wish, as a result, that people would stop touting it as a way to scale Zope apps. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Re: [Zope] Multithreading sessions

Jens, Thanks for your input. Unfortunately, I am out of the office this week. When I return I will be trying to resolve this issue. I don't believe it has squat to do with my Database at all, so I will be setting up some scenarios where I am making simultaneous requests, requiring no DB access. I will echo the data to my screen, hopefully I will see an interwoven jumble of characters as my web server is sending text "simultaneously" to multiple clients. If I don't see an interwoven jumble of stuff representing the various threads, then my problem is more fundamental than DB contention. I appreciate everyone's help.
