Management of HEAD requests
by Jesus Cea 15 Mar '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Using Zope 2.10 here. When making a HEAD request, I get the "last-modified" time of the script, and an "application/octet-stream" content type. The content length is the script length. When doing a GET request, I get a "last-modified" time of "now" and a "text/html" content type. And the length is correct here. As far as I know, the HEAD doesn't reach the script, it is processed inside Zope. I would rather prefer to actually process the script but give back only the headers. That is, my problem is that HEAD and GET of the same object provide completely different information about different objects (HEAD gives info about the actual script, GET gives info of the script output). This could be even a privacy issue, giving out script details people don't need to know. Is there any way to override this?. Suggestion? I have issues, for instance, managing RSS feeds, since some clients do a HEAD request instead of a conditional GET, for detecting new entries. Thanks in advance, folks.

zope programming: few queries
by KK CHN 08 Mar '11

List, Let me request your patience and time, I am a zope newbe trying to get some light in the darkness. I am trying to learn zope2 for the last couple of months, reading and doing zope2 documentations and sample file based python product developments. I know Zope s advanced a lot more than a decade(and zope3 / bluebream is the there now) but I just started few months back, sorry for my ignorance and lack of opportunity to start at the early stage. I have gone through zope2 docs and other tutorials on zope, and tried a couple of file base zope products. But I am unable to find/ do a complete user registration module for zope sites. and small session handling applications like a shopping cart which use session management techniques. 1 how zope.org is doing user login/register/password retrieval module, or how people like you add a user registration/login/password retrieval module for your zope sites. I searched a lot and learned the acl_users folder properites, and can do manually add users with these code excerpts. self.manage_addUserFolder() self.acl_users.userFolderAddUser('user1', 'passwd', ['Member','Admin'], [] ) self.acl_users.userFolderAddUser('user2', 'passwd', ['Member', 'Managers'], [] ) self.acl_users.userFolderAddUser('user3', 'passwd', ['Member', 'Manager','Admin'], []) etc. but unable to do a user registration module using acl_users and its web interface . By reading BetaBoring and some other tutorials in upfront systems zope course, devshed.com tutorials I think I am in the right track of zope2 learning. 2. I have done a sample application, but I dont know how to clear the normal zope user credentials when a sample user clicks a logout link here some sample code : I added an anchor <a href ="logout" > Logout </a> tag for logout in my pageTemplate name as myPage.zpt from AccessControl import ClassSecurityInfo security = ClassSecurityInfo() security.declareProtected('adminroles', 'myPage') myPage = PageTemplateFile( os.path.join('views', 'myPage.zpt'), globals()) and I added few sample users such as user1, user2, user3 etc to acl_users with sample password 'passwd' self.acl_users.userFolderAddUser('user1', 'passwd', ['Member','Admin'], [] ) self.acl_users.userFolderAddUser('user2', 'passwd', ['Member', 'Managers'], [] ) self.acl_users.userFolderAddUser('user3', 'passwd', ['Member', 'Manager','Admin'], []) and when I access the protected page 'myPage' it asks me for acl_user credentials and I am able to enter sample users and password and it allows me to view the page 'myPage' But problem when I click the Logout Link in the myPage( <a href="logout"> Logout</a>) then it call a logout.zpt page template there I display a message you logged out , and return the login.zpt page. but in the login.zpt page if you enter anything I mean garbage for username and password field it allows to view the myPage.( this happens once you logged in first time with the credentials). How to clear these zope acl_users credentials once you click the logout link which in turn call a logout.zpt template. If you have some sample / demo applications to show how to do these issues, can you share me those. I am stuck in this point in zope. if any such application code/related works to follow it will help me a lot. Thank You kkchn
