It wasn't a threat. You will note I stated, 'have to'. Trust me. After 6 weeks of developement to be 2 weeks from launch and discover a major problem with software foundational to the project brings out urgency as I am not personnally excited about having to move away from Zope. If I can't resolve the issue I will have no choice but to go to WebWare so that I can at least reuse some of the code. I didn't state it as a threat, it was not intended as a threat and if that was what was inferred I am not contrite. The subject was to show urgency as my previous emails on the subject went without notice or response. Someone at DC informed me that 2.4 is supposed to resolve the issue so I will have to try that. -----Original Message----- From: Chris Withers To: Pierce, Scott Cc: 'zope(a)zope.org' Sent: 5/20/2002 12:35 PM Subject: Re: [Zope] help before I have to dump zope So dump Zope then ;-) Chris - threats ain't a great way to solicit help...

Re: Virtual hosting How-To

> Are you using an older Zope? Actually I'm in the process of updating my Zope to the last version > In 2.5 a single Virtual Host Monster in the root > should be able to do the job much more simply. Actually I tried to use the Virtual Host Monster with my test site wich has the latest Zope version, but I couldn't get it work as I wanted: one or more virtual websites distributed through your Zope (not in one folder as many How-Tos do it). I found How-Tos wich talk about using it in conjunction with Apache but I won't install it. Is Apache necessary to get it work?. > If the basic Zope-only capabilities don't work > for you, check out > http://www.zope.org/Members/sfm/SiteAccessEnhanced. Actually, I don't like to install products that do virtual hosting. If Zope has a functionality that does it, why don't use it? Or if this product is necesary to do virtual hosting, then why is it not included with Zope? I also read the documents inside this product and found that they are the same as the ones here: http://www.zope.org/Members/4am/SiteAccess2/vhosting and if you see, they also recommend this old-style method as you call it. Anyway, if you point me to the right way, I could try your advice. Thanks for your reply, Josef.

help before I have to dump zope
by Pierce, Scott 20 May '02

20 May '02

I have a large number of DTMLFile objects generated within a product implemented like so: index_html = DTMLFile('www/index_html', globals()) standard_html_header = DTMLFile('www/standard_html_header', globals()) Tracks = DTMLFile('www/show_tracks', globals()) I can access these DTMLFile objects like so: http://someurl:8082/MyProduct/Tracks however, basic authentication does not follow, meaning, I always get anonymous user even after the browser prompts for credentials and I supply them. I am using zope 2.3.3 on a solaris box. I can't access these pages without the proper credentials, providing a user known in acl_folder with the proper role for viewing; however, the information is not provided in the REQUEST object so that I can use the user/role/permission info programmatically.

Mailing lists functionality
by Dan Stowell 20 May '02

20 May '02

Hi all, I'm new to this list so I apologise if I'm repeating old questions (though I've searched the list archive already). Does Zope provide the ability to have dynamically-generated email distribution lists? Does it provide the ability to maintain distribution lists at all (and to actually send the emails)? We don't have Zope installed, but it may be a possibility, and I'd like to know if it could be arranged that staff could sign themselves up to various email announcement lists while browsing a Zopey intranet. Many thanks in advance.

We've got enough hassles with screwing performance out of the system as it is right now. (and way, way, way too much to do to spend on tooling up for a major effort on making ZPT work faster).

Redirecting with Parameters
by Daniel.Dunbar 20 May '02

20 May '02

Hi I'm trying to redirect a client request. I'm using the RESPONSE.redirect ('URL') function and it works fine. I have however parameters in a form which needs to be sent along to the redirection page. This page is an intermidiate page for pages that load slowly i.e. a page which reads 'please wait ...' The parameters are therefore different from REQUEST to REQUEST. I appreciate your help on this.

This only helps if your pages are mostly static, or mostly the same for each user. Many/most of our pages are highly dynamic, this makes a front end cache a bit exciting. For RAM caching, we use a whole pile of different values as keys - languages, partner, that sort of thing. The sidebar on www.ekit.com is ram cached - right now, the ram cache has 320 different sidebar entries. Other things I found that helped (digging into the memory here): avoid dtml-tree. It _seems_ neat, but it's a total time sink. work out which SQL methods are getting hit, and when, and cache them.
