Hi, We've the following schema (see article : 'What is Zope?') : Web browser ! Zope Publisher ! Zope ORB Then... Module and inside the module we've the Object and Template Can I say that ZFramework is the same as the Object module or where do I've to situate this? Or there more then 1 Object modules? Are the object and modules not retrieved from the Object database? Tom.

Well, the way this is determined is pretty standard - the problem really is a lack of options on the part of the server, IMHO. As far as I know, IIS is really the _only_ web server where this couldn't be fixed totally through server configuration :) That is not to say that other options wouldn't be considered - if you have any suggestions for an alternate way of controlling the perceived URL, let me know and I will put them in the Collector as a feature request to make sure this issue is revisited.

It is so easy to have the same  refer to different objects via acquisition, and if you changed the reference  everywhere, it would break those which refer to a higher level acquisition. This is particularly twisted since you can construct URLs, such as adding the sql dir in as we have recently seen on the list, to effectively change what is meant by an acquired variable. I rather doubt that it would be very possible for some algorithmic code to guess when you meant to refer to this specific object, and when you meant to refer to this pattern of acquisition. After all, what if you are renaming the object so that you can revoke the acquisitive override without losing the functionality of the object? A SAR would break the acquisitive behavior you were trying to cause! Its sounds like a nice idea, but I see too many potential problems due to Acquisition. > Tom. > > > >Just as an aside: PrincipiaTime has been renamed to ZopeTime. > >Principia was the old name of the management interface, before it was > >merged with Bobo into Zope. > > > >-- > >Martijn Pieters, Web Developer > >| Antraciet http://www.antraciet.nl > >| Tel: +31-35-6254545 Fax: +31-35-6254555 > >| mailto:mj@antraciet.nl http://www.antraciet.nl/~mj > >| PGP: > http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 > >------------------------------------------ > > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

I want to actually redirect to another address which seems to always work no matter whether the the folder is allowed to be accessed or not. Here is the method I'm using

Great, it's going well. Other q'n :  How can I ask to write the date down as e.g. 29 Apr 1999? I tried fmt="day, aMonth, year" but it doesn't work... Do I've to call  3 times for getting this result? Tom.

Sounds like a reasonable solution, but out of interest, how does zope determine its base address anyway? Is it based on one of the environment variables passed in to the zope cgi? If so, is the problem that when using a isapi filter on iis, this variable does not reflect the change? If so, if I could fix that variable I suppose that would be a more general solution and I could use both relative address and the URLn variables. In any case, shouldn't there be a more flexible way of telling zope what its address really is?

Re: [Zope] ZServer ftp problem, when not running as root

Does it work correctly when run as root? If ZServer works differently depending on the uid it is run as there is a good chance that the problem is with the ownership of the var directory and its contents. The uid that the server is run as must have write permissions on the var directory and all files in the var directory. >This means, that uploaded files all have >length 0 or 144 bytes, depending on the version of zope.

I haven't heard of this kind of problem before, so I'd love a complete bug report. With enough information I may be able to help you solve this problem. Could you please file a report in the Collector and include information about what platform you are using, what version of Zope, what version of ZServer you are using, and how you have configured ZServer. It would also be useful to have an detailed list of what goes wrong, and under what circumstances. Thanks a lot! -Amos P.S. The Collector is at http://www.zope.org/Collector/

Content-Type: text/html <html> blah </html>  Should do it. It is very important that the Content-Type line be right below the start of the sendmail tag, and there *must* be a blank line after it. Also, while were on the subject, the mail you sent to the list was formatted in HTML. This is usualy a mail list faux pas (at least it is on this list). It is much easier for us to answer questions formatted in plain text. The chances of you getting an answer are much higher if you send plain text, that way we don't have to unformat your message into plain text and then hand quote it. It is also easier (for me at least) to use other mailers in conjunction with my usual one; all mailers handle plain text the normal way, but they all handle HTML in their specific way, which drives me nuts. ;) -Michel >Gilles
