Speaking of browser cache problems... It would be really nice to be able to set HTTP headers on objects other than dtml methods and documents. It would be very cool to be able to set HTTP properties on any object, or to at least be able to apply certain headers based on mime type. --sam Li Dongfeng wrote:
Yes, I have met this problem before. I don't know whether this is a server side problem or client side problem.
I'm using netscape navigator 4.7, When I cleared the disk and memery cache on the browser, the new image showed correctly. I would like to hear other solutions.

I am still struggling along with trying to get Zope (2.01 on Linux) to properly manage image *overwriting* for a web application that I am developing.
I previously posted about this (http://www.egroups.com/list/zope/md534753122.html)
here is some simple code to illustrate my problem :
I have a form that prompts users for
<input type="text" name="id" size="20"> <input type="file" name="image">
i.e. id is the name of image, and file is the file to be uploaded from the local file system to Zope. the action of this form is the added_new_staff method below :
<dtml-with REQUEST> <dtml-with "_[id]"> <dtml-call "manage_upload(REQUEST['image'])"> </dtml-with> </dtml-with>
Zope executes the above without complaint, but when I try to use the image in other methods, I get the *old* image. *BUT* when I try to view /image/image I see the new uploaded image......what is going on here ? It seems that I am running into a side effect of acquisition here, but I also notice that when you use Zope's builtin image uploading and updating through the management interface, I get the same behavior. Is this a bug or a feature ? Can I really overwrite an image in Zope ?
thanks for any helps,
Darcy
