Http API Ping
by Brendon Grunewald 10 Oct '01

10 Oct '01

Dear Zopistas, Quick Question: I need to ping an external url, but do not want the customer to click a submit button or something similar. i.e. if a certain page is viewed, I want to ping an HTTP API on another server in the following format: "http://www.sp.com/api/@param=abc". Depending on the parameter sent to them, I either need to store the result returned or ignore it and carry on regardless. This is similar to the way counters work, but I would prefer not using Javascripts. Is there a zope solution. <dtml-call ...> does not seem to work for external urls. Any assistance much appreciated...

Can anyone tell me why this doesn't show the contents of the "summary" property on DTML Documents? Folders and Structured Text Documents work just fine. <dl> <dtml-in expr="objectValues(['DTML Document', 'Folder', 'File', 'Structured Text Document'])" sort=title_or_id skip_unauthorized> <dt> <a href="<dtml-var absolute_url>"> <img src="<dtml-var icon>" border="0"> <dtml-var title_or_id></a> </dt> <dd> <dtml-with aq_explicit only> <dtml-var summary missing=""> </dtml-with> <p></p> </dd> </dtml-in> </dl> -- Matt Behrens <matt.behrens(a)kohler.com> System Analyst, Baker Furniture

There is 3 or 4 products for doing sessions. Cookieless Session Manager, Core Session tracking, etc...

CoreSession + Non-undoable databases
by CJ Kucera 10 Oct '01

10 Oct '01

I'm looking into CoreSessionTracking, and like what I see, but I've got a question. I want to have sessions persist beyond browser shut-off, which means I'll need a Session Data Container. In the docs, it's mentioned that the Data Container should be instantiated inside a non-undoing database. Well, I want to keep the undoability of the ZODB for most of my site, so how do I mount a non-undoable database somewhere in the tree? I've looked around at zope.org, and I've run into MountedStorage, but it seems to be out of date ("need a very recent CVS, the 2.2-pre releases aren't good enough," etc), so I'm wondering if there's a better way, or at least a Howto somewhere. Thanks again! -CJ WOW: Rapacious | A priest advised Voltaire on his death bed to apocalyptech.com/wow | renounce the devil.

AW: [Zope] POST with Content-Type : text/plain fails

Hannu wrote There is no such thing as text/plain content type for post request. What is the _real_ content type (format) of your external server ? Zope needs to know it in order to extract the data that is POSTed. The _real_ content type is plain text! The paramenters come in the mime-body as name1=value name2=value Armin

RE: [Zope] Zope and mime types ???
by Frank Stephan 10 Oct '01

10 Oct '01

> You probably cannot do anything to make sure that you get this MIME type > unless you map it yourself at the server. I understand, that there must be a mapping of the file extension to the appropriate mime type. I found in the mime.types file of my Apache config that there .doc is mapped to application/msword. But why does it still depend on the fact, that word is installed on the client or not? Mime/content types do not really make sense to me that way. Am I wrong or is there a way to control this on the server machine? TIA Frank
