Hi Steve,
Your solution is very cool! I'm going to use it in the following
form...
(maybe a bit more flexible?, change the default days to suit your needs)
ID: expireInNDays
Parameter List: self, days=1.0
_BODY__
t = self.ZopeTime() + days # user defined duration
t = t.toZone('GMT')
return t.strftime("%A, %d-%b-%Y %H:%M:%S GMT")
___
On the page you want to set the cookie put:
dtml-call "RESPONSE.setCookie('cookiename','cookievalue', path='/',
expires=expireInNDays(this(), 7.0))"
or, to use the default of 1 day:
dtml-call "RESPONSE.setCookie('cookiename','cookievalue', path='/',
expires=expireInNDays())"
Thanks -Eric.

[Zope] Cookies Expiration
I'm trying to set up something like is used in the Zope Elvis tutorial, where it sets a cookie to show when you last visited the site, so that I can flag certain articles as 'new'. However, I'd like to have this cookie set to expire one week from the date of the current visit. i.e., if its 12:30 on 11/3 when a surfer visits my site, I want Zope to set their lastVisited cookie to expire on 12:30 on 11/10. Any ideas?

Be careful with "cookies"!
The value of a cookie it quite severely restricted (must not contain
many characters; you read the cookie specification?).
In your case, the value is not a string at all but a
Zope object. "RESPONSE.setCookie" will probably convert the
object to a string for you. This will give you
"AUTHENTICATED_USER.getUsername()". However, I would feel
better, if this would be in your "setCookie" call.
Note, that probably Zope user names may contain characters not
allowed in Cookie values.
I'm still not able to click through to another hyperlink once I'm logged in,
i.e., I've used www.ddi.nl/support to go the password protected Zope site,
logged in as a customer, and from there I can choose other parts of the site
(below .../support/). However, www.ddi.nl is an alias of
www.datadistilleries.com (the actual name): as a result it asks me for the
password again. I thought setting the path to '/' would convince Zope I'm
authorized, but apparently it's not the case.
The path is a "local" path on your server.
Setting "path='/'" tells the browser to add the cookie to
any request going to your server. "path='/'" would tell
the browser to send it only for requests with paths beginning
with "/".
You cannot control with "path" to what server the cookie is
sent. There is the "domain" specification that gives you
some control over the servers that get the cookie.
I doubt, however, that this mechanism will allow you to
send cookies defined by "www.ddi.nl" also to
"www.datadistilleries.com".
2) This might be related to 1. I've created a logout link on the
/support/index_html page, which looks as follows:
dtml-call "RESPONSE.expireCookie('account',path='/')"
dtml-call
"RESPONSE.redirect('http://www.datadistilleries.com/support.html?section=m6envelope=6')"
However, once I've been redirected I can still access the password protected
/support/ site without Zope asking me for a login name.
There must be some magic, you did not yet tell us about.
Usually, setting a cookie has nothing to do with password
protection or authentication.
There must be something like a "login manager" that ties
Zope's security subsystem, login/logout and cookies together.
Usually, this "login manager" would do the cookie handling
transparently.
That you are concerned with the cookie seems to indicate
that you implement your own "login manager"?
The built in Zope authentication does not use cookies at all
but "basic authentication" as defined by HTTP.

[Zope] cookies don't obey me
I've been experiencing two problems with cookies from Zope:
1) When I set a cookie with the path set to the root
dtml-call "RESPONSE.setCookie('account',AUTHENTICATED_USER,path='/')"
I'm still not able to click through to another hyperlink once I'm logged in,
i.e., I've used www.ddi.nl/support to go the password protected Zope site,
logged in as a customer, and from there I can choose other parts of the site
(below .../support/). However, www.ddi.nl is an alias of
www.datadistilleries.com (the actual name): as a result it asks me for the
password again. I thought setting the path to '/' would convince Zope I'm
authorized, but apparently it's not the case.
2) This might be related to 1. I've created a logout link on the
.../support/index_html page, which looks as follows:
dtml-call "RESPONSE.expireCookie('account',path='/')"
dtml-call
"RESPONSE.redirect('http://www.datadistilleries.com/support.html?section=m6envelope=6')"
However, once I've been redirected I can still access the password protected
.../support/ site without Zope asking me for a login name.
Now, I'm not 'cookie guru', so please don't tell me how stupid it is of me
that I didn't think of this or that to make it work. I did do my background
research homework though!
Thanks for reading this far ;-).

Subject: [Zope] Cookies
I am trying to create a cookie based on the value returned from a sql
method. The following code fails with an invalid syntax error.
dtml-in SQL_get_cntry
dtml-call "RESPONSE.setCookie('country_cookie', dtml-var cntry_cd)"
dtml-in
Hi,
Inside quotation marks, you're writing python, so dtml-var cntry_cd makes
the parser barf. cntry_cd is pushed onto the namespace by the dtml-in, so
you can simply use:
dtml-in SQL_get_cntry
dtml-call "RESPONSE.setCookie('country_cookie', cntry_cd)"
/dtml-in
Note also the slash in the closing /dtml-in.
hth,
