You don't HAVE to, but the optimal configuration is to have one interpreter per CPU, yes. So if you start an instance, you should bind it to a specific CPU. It'll work fine even if you don't do it, but performance won't be optimal. I've moved away from multi-cpu machine for my Zope because of this, makes things much easier.

Re: [Zope] Its nope with zope , parameter prob remains

I suggest a different approach to this problem. Instead of priming the option lists in a page template try the following: 1. put only <option value="selectdistrict" selected> in the select lists. 2. put the data in Javascript arrays: districts = new Array("district1", "district2") districts["district1"].users=new Array("UserName1", "Username2"), districts["district2"].users=new Array("UserName3", "Username4") 3. Use onLoad to prime the districts options (use a function to add options in districts array) and onClick to change the Username options. Some people might suggest that sending a list of usernames is a bad idea. Leaving that bit out would save you a lot of work and avoid the accessibility issue with onClick. Cliff P.S.

Re: [Zope] opening a ZPT from a script
by Leticia Larrosa 11 Mar '05

Thanks to Chris for response me, and I want that him excuse me, because I have an imprecision, and I feel very embarrassed because in the "The Zope Book (2.6 Edition) Amos Latteier, Michel Pelletier, Chris McDonough, Peter Sabaini" the example is: " pt = context.hello_world_pt s = pt(name="John Doe") return s " And I asume that when I call a ZPT without parameters is: "return context.hello_world_pt", whereas whit parameters are same that the example. In spite of the above the "return context.hello_world_pt" in some cases works ok, and in others case return the zope object reference, instead of make a call to the object (in this case a ZPT). Thanks to Chris Withers Thanks to all !!!! -----Original Message----- From: Chris Withers To: Leticia Larrosa Cc: zope(a)zope.org Date: Fri, 11 Mar 2005 15:25:46 +0000 Subject: Re: [Zope] opening a ZPT from a script > Leticia Larrosa wrote: > > "return context.ss" and works ok to.

Does Zope support HTTP Trace method??
by Jay Zeemer 11 Mar '05

11 Mar '05

Greetings All, In a lot of HTTP servers there is a method used for debugging sessions and such called TRACE. Does Zope support this?? And if so is it active, or inactive by default?? How can I turn this on and off?? Jay

how to set request http status.
by bahriesz＠yahoo.com 11 Mar '05

11 Mar '05

How do we set the http status of the Request reply back to browser?. This is needed in situation where we defined our own http status. Those you are familiar with snakelets framework, there is request.send_error(code, message). thanks. __________________________________ Do you Yahoo!? Yahoo!

RE: [Zope] Does Zope support HTTP Trace method??
by Jay Zeemer 11 Mar '05

Actually if you query the Zope web service to see what it supports it tells you: Allowed HTTP Methods: GET, HEAD, POST, PUT, DELETE, OPTIONS, TRACE, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, UNLOCK TRACE allows for some XSS problems and I just want to make sure I have the server locked down against as many vulnerbilities as I can. I can not find any mention of the Zope Web Server supporting TRACE so I am trying to find out if it actually does support it or if its just reacting to the query. The tool I used is called Nikto, its just an HTTP assult tool. It looks through a predefined list like Nessus, but restricts its self to possible HTTP issues. It also plays a lot nicer on a network :) Jay -----Original Message----- From: Chris Withers [mailto:chris@simplistix.co.uk] Sent: Friday, March 11, 2005 10:35 AM To: Jay Zeemer Cc: 'zope(a)zope.org' List Mailing Subject: Re: [Zope] Does Zope support HTTP Trace method??

How can I turn this on and off?? I'm not aware of any TRACE support in Zope. You run it behind Apache maybe? You been poking with Nessus? ;-) Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
