My Zope application dynamically creates and modifies image files based on form input. I need a way to prevent these images from being improperly cached by the user's browser. What I would like is to force all images within a certain directory tree to return the appropriate header magic to prevent browsers from caching. Is there a clean way to do this? -Greg LEGAL NOTICE Unless expressly stated otherwise, this message is confidential and may be privileged. It is intended for the addressee(s) only.

there was a mailing list discussion abt this some weeks ago, what it came down to was like appending the image-url with a unique number (DateTime probably is enough) to prevent browser caching. ------------------------------------------------------------- Who's got only a hammer sees the world as a nail hans augustin (software developer) hans@beehive.de beehive elektronische medien GmbH http://www.beehive.de phone: +49 30 847-82 0 fax: +49 30 847-82 299
