After reading this, I'm not sure I understand what the core problem is - is it that the REQUEST was not available as an explicit argument, or am I missing something deeper here?

Re: [Zope] zope.org speed
by Thomas B. Passin 02 Nov '99

Nope, a lot of the speed increase came before any hardware change. See posts to this group over the last few days. They changed returned headers so browsers can do more intelligent caching, and they increased the Zope-side object caching. After this, I saw a dramatic improvement - no hardware involved. It would be useful to see the exact details of how they did it so the rest of us can too.

Re: [Zope] Cookies

Yep, you can do it. Cookies require a very specific expiration time format: '%a, %d-%b-%Y %H:%M:%S GMT' So, to set the expiration to one week in the future, you can use something like (untested): <dtml-call "REQUEST.set('expires', ZopeTime() + 7)"> <dtml-call "RESPONSE.setCookie('mycookie', 'myvalue', expires=expires.strftime('%a, %d-%b-%Y %H:%M:%S GMT'))"> Kevin -----Original Message----- From: Chui Tey <teyc(a)bigfoot.com> To: zope(a)zope.org <zope(a)zope.org> Date: Tuesday, November 02, 1999 4:26 AM Subject: [Zope] Cookies Hi everyone, I must be dense. I have tried and failed to make cookies persist beyond the current browser session. Is this option available? Thanks in advance. Chui

Re: [Zope] How can I rename an object from inside DTML?
by Kevin Dangoor 02 Nov '99

When you say "trying to rename itself", I assume you mean that the manage_renameObject call below is actually done in a method of 'white_wine's ZClass. manage_renameObject should actually be called on the ObjectManager that contains white_wine. You could probably do: <dtml-call "PARENTS[1].manage_renameObject(id, _.string.replace(REQUEST['name_singular'],'', '_'))"> (Not sure about those last couple parameters.... my main point was just that tacking a PARENTS[1] onto the beginning could fix it.)
