Reinventing a proxy wheel?
by Gaute Amundsen 03 Jun '08

03 Jun '08

Hi. I think I may just have reinvented a kind of cgi-proxy for authentication purposes. Seems to work nicely so far, but oh, so ugly. Thus I would be gratefull for any pointers towards some more enlightened solution. Problem to solve: External php based facility needs to be made available to logged in zope users only, but have no built in mechanism to to handle "everyone must log in to see anything at all" situations. Some users can be synced by way of sql, but many can not. This is a given. My solution so far: An external method that wraps wget. Rearanges the url to connect via 127.0.0.1, and use original host as host header. Use Apache to close access to everyone but 127.0.0.1. Rest of the script basically shuffles headers back and forth from zope to wget, and back. and the script can of course be subject to normal zope access checks. If no major flaws with this approach appears, I will of course replace wget with urllib, and perhaps even productify the thing, but before I do that I have this nagging feeling of reinventing the wheel that I need to address... Regards Gaute Amundsen

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.
