Re: [Zope] Cache values may only be in one cache
Product refreshing is a brilliant timesaver for development if it suits your development style. Some people prefer to restart Zope on every change which is the only option for Zope 2.9 and Zope 2.8. The error is somehow related to the use of the Session Manager I think. If you instead use my Zope refreshing script http://www.fry-it.com/at/refresh-my-zope-products unlike automatic refreshing which comes out-of-the-box in Zope, the refresh is done before you reload the page which means that you won't no longer see this error message.

Every time you change the object or push the "invalidate" button, it should expire.

RE: [Zope] Cache concerns (was zope/proxy_pass configuration problem)
Ragnar,
Caching is a subject I'm not all that familiar with but one I need to learn
really fast. My site is about to go live, and I have a monster of a query
that will bring my system to its knees if 100 students run it at a time. So
I'm sending this off to the Zope mailing list wondering if anyone can give
us some caching/performance tips.
- T.J.

Subject: RE: [Zope] zope/proxy_pass configuration problem
Very good idea! I tried it and it works like a charm :) Thanks a lot!
One problem is left over: apache doesn't cache the documents although I have
dtml-call "RESPONSE.setHeader('Expires',
_.DateTime(_.DateTime().timeTime() + 3600).toZone('GMT').rfc822())"
in my standard_html_header. ab -n 100 -c 1
http://www.dummy.com/index_html shows 100 queries in Z2.log where
there should be only one.
What could I be doing wrong?
Ragnar
Ragnar,
If you're referring to my ZServer+Apache+SSL HOWTO, this would be a
problem.
Going in through https will only give you access to the 'ssl' directory.
The quick dirty solution (while retaining the ability to distinguish
between http and https) is to reverse the setup, i.e. place the https
SiteRoot in the main folder and create a separate folder called, say,
'http', which holds the http SiteRoot. This solution will kill two birds
with one stone: it will grant access to the entire site via https while
restricting http users to an empty subdirectory.
Hope this helps,
T.J.

Subject: [Zope] zope/proxy_pass configuration problem
Hi Zope-Configuristas!
I would finally like to say goodbye to pcgi but one thing keeps me
hooked. I tried and tried but the solution just won't appear. Here is
the problem:
I have a site that is supposed to be reachable via http as well as
via https. That's not a problem per se. Configuration of zope with
proxy_pass is easy as can be. The problem is that management shall be
possible via https _only_ (for obvious reasons). But as soon as I use
site access to define the http-branch this branch is not
managable/accessable via https any more. Is there a solution?
Ragnar

How can I disable the browser cache in my zope documents ?
One thing you can do is set the 'Expires' header like so:
dtml-call "RESPONSE.setHeader('Expires', _.DateTime().rfc822())"
This works using Netscape. But for IE I had to use:
dtml-call "RESPONSE.setHeader('Expires', '-1')"
dtml-call "RESPONSE.setHeader('Cache-Control', 'no-cache')"
dtml-call "RESPONSE.setHeader('Pragma', 'no-cache')"
I think the last Pragma can be left out. But the Cache-Control header
ist neccessary. I got the information out of rfc2616.

RE: [Zope] Cache
Does this work in IE5? I'm using similar META tags which work for IE4 and
Netscape but don't work in IE5.
